Betta Fish Care – Create A Thriving Betta Tank

The Betta Fish for some of us fish keepers was our first experience with a pet fish. It was our introduction into this wonderful world of aquarium keeping. Betta Fish after all have a lot going for them that make them great pets. They have a great personality and come in a variety of colors. They can exist in smaller tanks and can be relatively hardy as long as the environment is properly cared for. 

The main issue with Betta Fish care is that they can be seen as this indestructible fish that can live in just about anything. There are some misconceptions about these fish. Other times, because this is the first time that some of us kept a pet fish, we lack information and experience to make us successful.

This Betta Fish guide is written with the purpose to help you with proper care and all the main elements that you need to know about being successful with Betta fish. We will go over proper housing, filtration, heating, decor, diet, and tankmates. We will then put it all together and build out a complete Betta Fish tank. As quick disclosure, this blog post will contain affiliate links which I may get a small commission at no extra cost to you should you make a purchase. Ready to get started?

All About the Betta Fish 

The Betta Fish’s scientific name is Betta splendens. They are also know as Siamese Fighting Fish. They originate from Asia and were kept in the past for their fighting nature. They were first imported to the US in 1927. These days, Bettas are primarly kept for there appearance. They have been selectivity breed over the years into many different color and tail types. They are now known as the designer fish in the freshwater hobby. 

In the wild, Betta splendens originate from Southeat Asia. They are native to areas that are visited by frequent flooding that will also go through periods intense droughts afterwards. As a result, Betta evolved to become a labyrinth fish. A labyrinth is a fish that has the ability to take in oxygen from the air as well as take oxygen from its grills. Because of this adaption, Bettas have the ability to live outside of water for short periods of time and can breath air around them provided they can stay moist. This is the reason why you tend to see Bettas in small containers at the pet store or at home (though I would not recommend this — more on this as we through this post). 

Betta is pronounced Bet-tah. It is very common for newcomers to pronounce it as Bay-tah. They received their name from the ancient Asian “Bettah” warrior clan. They were discovered in Thailand. Their Thai nae is Iken Bettah, which is translated as “biting fish.” They are also known as Siamese fighting fish. This name was taken from the word Siam, with Siam being the former name of Thailand. They became very popular in the mid-1800s for their fighting. The fighting sport became so popular that the King of Thaliand ended up regulating the sport and taxing it. The sport competitions were actually measured on the fish’s bravery versus the damage they inflicted on their opponent however. 

Betta Fish Male and Female Differences

Males and females are distinctly different when it comes to Betta Fish. The males are generally more colorful with larger fins. Females have shorter fins and generally more dull in color. Male siamese fighting fish also tend to have a more torpedo shaped and larger body. Females also have an Ovipositor on the under size of their body. These are tiny tubs that release eggs.

Betta Male versus Female

The International Betta Congress (Betta Fish Competitions)

Betta Fish breeding has been very popular over the years with breeders raising some of the most beautiful fish you will ever see in the hobby. In fact, there are competitions for show Bettas (pronounced Bet-uh) hosted by the International Betta Congress (IBC). Below is a video by DocAquaTV showing an IBC competition in full swing. There is a huge community when it comes to Betta Fish, and seeing these unique looking and high quality Betta is a real treat. 

I would highly encourage anyone who is passionate about keeping these fish look into a scientific based community like the International Betta Congress and maybe even think about joining to deep drive into the Betta world. They offer a lot of benefits like their membership forum and magazine. They have been around since 1967 and really take efforts to bring education and care to Bettas all over the world.

Betta Fish Care – The Major Factors We Need To Know

Now that we know a little bit about the Betta itself and the scientific based community that supports them, let’s talk about how to take care of one. We are going to split care for a Betta Fish into the following elements:

  1. Housing
  2. Filtration
  3. Heating
  4. Decor
  5. Diet
  6. Tank Mates

Betta Fish Tank (Housing)

I’m going to be very upfront and clear to my readers here with this statement. The best aquarium to start with for a Betta is a 5 gallon tank. That’s correct, a 5 gallons. You may be a little taken aback from this statement as you may have visited your pet store and seen many of the “Betta tanks” available for sale. Many of them are badly undersized. 

5 Gallon Aquarium

I encourage anyone who is keeping a Betta Fish long-term invest in a proper 5 Gallon Aquarium like the one from Marineland shown above. Betta fish live best in a good sized tank and you want the best for your pet. Invest in the proper tank so your fish can thrive.

We also want to limit the number of male bettas in our aquariums. We should only have 1 male betta in our aquarium unless we are using tank dividers to keep our male bettas separated.Keeping more than 1 males is going to require more than 5 gallons. A 20 gallon tank is best for housing multiple male betta – 3 to 4 are best for a 20 gallon tank using a 1 betta for every 5 gallons approach.

Betta Fish Tank Filtration

Contrary to what you may see in at the chain pet stores, Betta fish are not best served in a fish bowl. We want their tanks filtered. This will make it easier to maintain as a fish tank without a filter is going to need a water change every 2 to 3 days. This can get very old fast! We want to make maintenance easy to do rather than a major chore. Having proper filtration in your tank will provide a proper nitrogen cycle for your fish tank and for your Betta. This will cut down the amount of times you will need to change water every month and give your Betta a better environment to grow and thrive. I would recommend a Power Filter if you are not using an aquarium kit or all in one tank. The best power filter for a small tank like these are going to be a Penn Plex Power Filter or Aquaclear as these companies design power filters at this size and both are adjustable. 

Hagen Aquaclear

When using a power filter, keep in mind that you will still need to protect your Betta. Bettas are known for having delicate fins and being very curious. It’s pretty common for them to get sucked into a filter accidentally or having one of their fins damaged. You will want to dampen the intake of your filter by putting a sponge over it and adjust the flow to make it more calm and suitable for the Betta. Bettas prefer calmer waters and some power filters on the market are designed for higher gallon per hour applications. Adjust it down for your Betta and let them adjust to the flow. 

Bettas and Water (Tap water and Bettas)

Because Siamese fighting fish have are labyrinth fish, it is a common misconception to put them in any type of water. While we can use tap water, we want to make sure we have the right type of tap water. Tap water needs to chlorinated with proper water conditioner produce like Seachem Prime. Water conditioners like Seachem Prime will remove chlorine, harmful chemicals, ammonia, and nitrite from your tap.

Never stick a Betta is straight tap water. Always make sure to de-chlorinate tap water to keep your fish safe.

Betta Fish Tank Heating (Water Temperature for Bettas)

It may not seem like it because you see many of these Betta for sale at the pet stores in bowls or small tanks, but they are actually tropical fish. They are most comfortable with water temperatures at 75 to 82 degrees with 78 degrees being your target temperature. I would recommend choosing a quality heater from our Best Aquarium Heaters Reviews post. Eheim heaters are one of the most reliable heaters on the market and are worth a look. Neo Therm Heaters are great as well. They have a smaller footprint that works better with the smaller size of the Betta Fish tanks and will fit in all in one tank chambers. Both heaters are accurate up to 1 degree of water temperature, the best in our industry.

Neo Therm Heaters

I would also highly recommend that you get a Digital Thermometer as a backup for your heater’s internal thermometer. If you have the budget, you can invest in a proper Aquarium Heater Controller for a more full proof water temperature regulation system.

Betta Fish Tank Decorations

There are two parts of Decor when it comes to Betta Fish, plants and hardscape (rocks and branches). For plants, specifically artificial plants (I’ll touch on live plants later in the post), we need to be very selective on what we put in our Betta Fish tank.

Aquarium Silk Plants

Silk plants like the Marina Naturals Plant shown above is what we want to purchase for our Bettas. Traditional plastic plants you will see at the pet store are not safe for a Betta Fish. This is because many will contain sharp edges and do not give way if the Betta runs into them. This leads to the delicate fins of the Betta Fish getting torn up which in turn causes injury and possible infection. We want to prevent as much harm to the delicate fins of our Betta, so let’s stay away from the hard plastic plants if we are going to shop for artificial plants. 

For hardscaping like rocks, we again want to watch out for sharp edges. Hardscaping for Betta Fish needs to be soft or round. You should be able to run your fingers through the hardscape and not get your fingers caught. If your fingers get caught, you have rough edges that will be dangerous to your Betta. Either consider sanding down the hardscape or picking another one. 

Another factor to consider with Betta decorations is to watch out for rocks and other hardscaping with lots of small holes. Betta Fish have a tenancy to get caught or stuck in holes. I would recommend that you purchased smooth round rocks or rocks with larger holes that your Betta will not get stuck in. 

Smooth Rock for Betta Fish

The image above is a good example of a hardscape that is suitable for a Betta Fish. This Coconut Shell is smooth and the hole is large enough to fit the Betta without it get caught or stuck inside.

Betta Fish Diet (Feed Your Betta Fish Right!)

A Betta Fish is a fish with lots of vibrant colors. In order to get these colors to show their best, we want to have a quality diet for our pet Betta. The fish food hierarchy in today’s hobby is frozen food, fried dried, pellet, then flake food. We want to be selective in what we feed our Betta fish so I will help with the break down. Lets feed your Betta the best food available.

Frozen food is at the top of our list because you can get some of the highest quality blends and mixes. Unfortunately, frozen foods are going to be the one food you will have a hard time finding online. Even if you do find it, the shipping costs can be expensive to the point where it is not worth it. Do yourself and your local store a favor and pick these up locally. I would recommend frozen blood worms, black worms, and daphnia. All can be found at your local pet stores. 

Next would be freeze dried. For freeze dried. I would recommend either freeze dried Blood Worms or Black Worms. The great thing with freeze dried foods is because they are dehydrated foods, they will soak up vitamin supplements. Consider supplementing your food with a product like VitaChem to boost your Betta’s immunity system and keep them healthy. Mixing VitaChem plus Blackworms is a great nutritional mix to feed your betta fish.

Fried Dried Blackworms

One thing to note in this blog post is I am not recommending brine shrimp as a food source. You may be wondering why I don’t when many fish stores and bloggers are happy to recommend. I do not recommend brine shrimp because there are way better food sources you can feed your fish. It’s great if you are in pinch or there store doesn’t have much else or if you have a picky fish. Brine shrimp just low on nutritional value. We can do better so why not?

Pellet food would be the next food I would touch on. There is really only one pellet food I would recommend for a Betta. That would be NorthFin’s Betta Bits Food

Northfin Betta Bits Food

Pellet fish should be presoaked before giving to your Betta. This will prevent the pellets from expanding in your Betta’s stomach and causing issues like bloat or constipation. You can also soak pellet food with vitamins.

Flake food I generally tend to avoid. Many types of flake food in our industry are simply not up to snuff for our fish and it’s hard to soak them in vitamins. If you want to go with flake food to feed your betta fish, I would consider a flake food with probiotics. One such flake food that comes to mind would be Cobalt Aquatics Tropical Fish Color Formula. It is flake food loaded with probiotics and one of the mainstream flake foods around that I would be okay with recommending.

Cobalt Aquatics Probiotic Flake Food.  

You may have noticed I did not mention live food in this discussion about Betta food. This is because live food has its major pros and cons. The main benefit with live food is the live bacterial cultures that you are feeding your Betta. These are priceless nutrition for your fish and truly can extend the lifespan and quality of live for your pet. However, there are major cons with live food. The biggest issue is disease and poor quality live food. You really need to do your due diligence if you are going to feed live foods to your Betta fish. It may even be better to grow them yourself if you really want or find a very trusted retailer who sells them. For live foods, I would highly recommend blackworms. Earthworms are also another natural source that you can pull from your garden and feed to your Betta if you are willing to cut them into bits. Microworms would be another live food to look at. All three of these can be cultured at home if you are willing to do so. I included a video from AquaStudent below explaining how to keep blackworms. It’s probably more relevant to Keeping Cichlids given how much you can grow, but I wanted to provide it anyway for your reference. If you take care with live food, you can have success with them. It’s just not something I would not consider for a beginner.

Tank Mates For Betta Fish

I’ll start this section with a very honest statement. Not every Betta is meant for a community tank. There is also the size of the tank you need to consider as tank mates in a Betta Fish tank should not be considered unless you have an aquarium 10 gallons or larger in size. To maintain the lowest levels of aggression possible with these mixed setups, a planted tank setup is going to be key to keeping the fighting down.

I’ll provide a list below than explain after. I’m going to start from safest to riskiest. The best tank mates for a Betta Fish are:

  1. Snails
  2. Shrimp
  3. Coryadoras
  4. Plecos
  5. Schooling Fish

Snails are going to be our best test tank mate to start with. Snails are low risk to add in an aquarium and we can take time to observe our Betta’s reaction to them. If your Betta is nipping at the antennas of the nails, this is a likely sign that your particular Betta is not going to accept tank mates readily.

If snails are not harassed, then we can attempt the next set of possible tank mates. These would be Freshwater Aquarium Shrimp like Cherry or Ghost shrimp. If your Betta is not attacking snails, there is a good chance they will leave pet shrimp alone. The great thing with shrimp is they are colorful and can be used to contrast your Betta colors. Be careful of overpopulation though as shrimp can breed rapidly.

The next set of teammates would be bottom dwelling fish like Coradora and Pleco. Because we are working with fish who inhabit a different section of our tank area, it is likely that both sets of species will leave each other alone. 

Cory and Betta

The final and riskiest set of tank mates are going to be school fish like Tetras and Rasboras. The activity level of these the fish may actually stress out the more calm Betta. We have to observe their interactions and watch for warning signs. It is very possible to have a Betta that lives happily in a tank with schooling fish.

Bettas are naturally solo fish though. To add tank mates into a aquarium with a Betta is asking the fish to adapt outside of its natural tendencies. Take your time and be patient. Be ready to make changes with your tank mates if things do not work out well for you.

Another thing I forgot to mention in this section is DO NOT place two males in the same aquarium. Males fighting is how the Bettas got their Siamese Fighting fish name from. Two males will fight to the death in an aquarium. Avoid placing two males in the same aquarium at all costs.

Male Bettas will also show aggression to females. It is best if you want multiple Bettas in your aquarium to go female only. Females are not as colorful as males, but a group of 5 females will compliment the colors of your tank as they have unique colors and fins in their own right. Keep in mind that a group of female Bettas will require a larger tank and there are really no guarantees with their compatibility as they reach maturity.

Live Plants for Betta Fish

Betta in Planted Tank

Live plants are a wonderful addition for your Betta. Not only do they add natural hiding spots for your Betta, they are natural filtration in your aquarium. I recommend live plants for most freshwater setups because they are great for improving water quality. Some plants are also know for being natural water conditioners as they can remove harmful chemicals in your water.

I would highly recommend Low Light Aquarium Plants for your aquarium. Keep in mind that if you do decide to go with live plants, to get a Planted Tank LED fixture that can grow plants. I am recommending low light plants because they are easy to grow and keep. However, many lights that come with starter aquariums will not have the proper light to grow even low light aquarium plants.

Finnex FugeRay

For tanks these small, there is a Finnex FugeRay model that is available that will aquately cover a standard 5 gallon tank. Another option is a Fluval Plant Bluetooth Nano. The Fluval nano is a perfect light for desktop aquariums.

With one of these lights, you are set to grow just about any low light aquarium plant you can acquire. For low light plants here are several you can obtain that would work will in a Betta tank:

Types Of Betta Fish

There are actually a large variety of Betta Fish available for sale in our hobby. Most of the Bettas you will see that the pet store will not have a specific breed or type listed. There are actually large number available varieties with Bettas. Many have exotic colors and fins. I’m going to talk about several here to show you the vast variety of Bettas available today. If you are shopping online for exotic style Betta Fish, I would highly recommend that you purchase from a place that offers What You See Is What You Get (WYSIWYG) fish for purchase and from a place that offers you a multiple day guarantee.

Veil Tail

Veil Tail Betta Fish

The Veil Tail Betta is the most common Betta you will find at a pet store. They are often labeled as Siamese Fighting Fish at chain pet stores. It is very likely if you are reading this article after you have purchased a Betta yourself that you have a Veil Tail. They are the most widely available Betta in the hobby. After all, this was the original domestic Betta that was brought over to the US. They are also one of the easiest Betta Fish to breed. These Bettas are known for their easy going nature and one of the better candidates for a community tank. 

Half Moon

Halfmoon Betta Fish

The Half Moon Betta is a Betta that is bred and raised in captivity. It gets it’s name it’s tail that spreads 180 degrees to form the half moon. It is a very striking Betta to have. It is notorious for being a very challenging Betta to breed. They are becoming one of the easier to find exotic Betta types nowadays due to their popularity. It was first bred in the 1980s. Half Moon Bettas are also known for their aggressiveness. They are best suited to be solo in an aquarium. Many of the fancier Bettas tend to be only available through local breeders, specialty fish stores, or online.

Rose Tail

Rose Tail Betta Fish

A Rosa Tail is a variation of the Half Moon. The ends of their tails are more ruffled creating a striking appearance. Like the Half Moon, they are also very difficult to breed. It requires a genetic mutation to occur to get the look and as a result they tend not to be as hardy as other Betta fish. They are an amazing looking Betta

Plakats

Plakat Betta Fish

Plakats are a short finned version of the traditional Betta you find in stores. Plakats are the original Betta and very close to the ones you will find in the wild. They are known as the ancestors of all Bettas in the trade today. They tend to be more actively swimming fish over the other fancier varieties and tend to do better in larger tanks as a result. It is actually possible to find a Halfmoon Plakat from a breeder. Given the fact the the Plakat Betta is closer to a wild Betta, they tend to be hardier, less prone to injury, and more energetic then fancier Bettas. 

Purchasing a fancy Plakat fish are a good balance if you want a fancy Betta, but would prefer a hardier and more active sub-type. The price above is a Halfmoon Plakat.

Elephant Ear Betta

Elephant Ear Betta Fish

These Bettas get their names from their pectoral fins that look like the ear of an elephant. These are one of the more exotic and striking Betta you will find. These varieties can also be found in the wild (though with less bold colors then their captive bred varieties). They are an aggressive Betta and best suited as a sole specimen. They slow down a lot later in life, so a calm tank alone is the best for them.

Crowntail Betta

Crowntail Betta Fish

This unique looking variety has a web fins that resemble a crown. It is one of the new varieties among breeders debuting in 1997. This Betta variety produces some of the most exotic colors and mixes available in the trade. Because of its breeding though, this also makes it one of the more difficult Betta to find and take care of. They are more delicate than the other Bettas on the list. It requires exceptionally higher water quality for its fins to stay healthy.  

Putting It Together – Creating A Betta Fish Tank

We spent quite a bit of time talking about Bettas,their care requirements, food, and types of Bettas. It’s time to put it all together and built a setup for you. I’m going to use a Fluval Spec V for this build. It is an all in one tank with 5 gallons as its volume. The tank really solves a lot of issues for us, namely the filtration and the lighting. The lighting that comes with the unit can grow Low Light Aquarium Plants and the aquarium size is ideal for our Betta. You can use any Aquarium Substrate you want since both Java Fern and Java Moss are water column feeders so either will do fine without  an active substrate.

We can either use a simple aquascape or get fancy with some Driftwood, taking care to ensure it has no sharp edges by sanding down any rough spots. If we go with driftwood, we can attach the moss and ferns to the hardscape with either thread or superglue. Below is a video by Fishaholic showing how to attach Java Fern to driftwood.

Betta Tank Water Quality

Now that you have your Betta tank, you may have questions about water quality. Bettas in general are hardy fish, with fancy sub-types begin more sensitive. We want to keep our water quality in good condition with water changes. I would recommend doing water changes weekly about 15-20%. You can reduce the water changes if your water quality is high. I always say water change to based on your water parameters. Get used to testing your water every week using a high quality aquarium water test kit and always use a water conditioner on your tap water.. Some tanks can go bi-monthly or monthly depending on how well the tank is filtered. Check for ammonia, nitrite, and nitrate levels. Ammonia and nitrite should be at 0 and keep your nitrates below 25. 

For pH, Bettas are pretty tolerant of neutral to soft water. They are best with a neutral pH of 7. They will do fine in a slightly acidic pH if accumulated to it, but as close to 7 as possible is ideal.

Additional Resources (Betta Fish Books To Read)

There are some incredible books available about Bettas that go beyond the scope of this blog post. I would encourage you to look into these books and purchase them if you are serious about taking your Betta Fish keeping to another level.

The Betta Bible

The Betta Bible is the source when it comes to knowledge about Betta Keeping. It is an expensive book, but well worth it. It is loaded with detailed and expert level information. It has information about genetics of Bettas, breeding, and history of the Bettas in our hobby. It is loaded with over 150 pictures of various types of Bettas and the style of writing is very down to earth.

The Betta Bible

Written by Dr. Brammah, this book has been known in the hobby as the book of all books. It’s a must buy in my opinion. The kindle version is a steal at the price if you can get that. It is everything you would want to know and more about Bettas jammed packed into 300 pages.

Betta Fish: The Simple Guide

If the Betta Bible is too much to start with, the Betta Fish book by Walter James is a good alternative. Weighing in at only 124 pages, it is a more digestible deep dive into Betta Fish keeping.

Closing Thoughts on Betta Care

A Betta Fish tank is in my mind the best way to introduce yourself to the wonderful world of aquarium keeping. A Betta tank can be small and low on maintenance making it a lower barrier to entry than other aquarium setups. There are a large variety of Betta breeds and colors. It is difficult to really get bored keeping Betta because there is no much variety and they are loaded with personality. If you have any questions, leave a comment below. Thank you for reading.

Chloroquine Phosphate - It's Not A COVID Cure Damnit 😆!
I'm really frustrated and tired of the news about Chloroquine Phosphate. There is so much bad information about Chloroquine Phosphate it has gotten to the point where it's affecting my business. I've been in the marine fish keeping industry for over 20 years. I've used this substance on marine fish in quarantine for ages quietly speaking its praises to my fellow hobby club and group members. It's been my secret weapon for years in battling the most deadly marine fish diseases over the years.
