Choosing the Right Pet Seahorse: Why Captive Bred is Best

Aquarists are encouraged to opt for captive bred seahorses rather than wild ones. These chosen specimens carry a reduced risk of pathogens and possess higher survival rates compared to their non-captive counterparts caught in nets or the wild. Captive breeding has also made it easier as these magnificent creatures can now easily be acquired from your local fish shop or qualified breeders.

Not only does selecting captive bred animals assist with keeping an intact habitat, but they have usually acclimated better when placed into aquariums. You will find that frozen foods such as mysis shrimp and brine shrimp tend to be more accepted by them, which helps ensure your pet is obtaining all necessary dietary requirements. Ultimately, choose carefully wherever possible. Always pick those born in captivity!

Creating The Ideal Tank

The health of your aquatic pets hinges on having a perfect seahorse tank. Make sure to provide ample space– at least 30 gallons per pair is optimal, with 50 or larger being preferable– and adequate vertical height (24” minimum) for courtship rituals. Be cautious when picking compatible fish, as the more aggressive varieties may harm seahorses due to their limited swimming ability. Maintain good water quality through protein skimmers, filter flosses or socks in order to control messy eating habits. Secure steady flow without strong currents that could endanger the safety of your pet seahorses. An aquarium sump is preferred for added stability.

Tank Size And Vertical Space

When it comes to seahorse aquariums, a reef tank or other type of fish tank should include plenty of vertical height. This is due to the fact that these fascinating creatures possess small fins which allow them swim in an upright posture through the water column. Allowing sufficient space for this maneuvering eliminates any risk of stress and harm caused by lack of room during their unique movements such as swimming and courtship dancing rituals. Cube aquariums excel for providing that extra height.

Maintaining Optimal Water Conditions

Seahorse keepers must ensure that the aquatic environment for their pet seahorses remains stable and safe. The water temperature should typically be kept between 68°F to 74°F, while filtration systems are essential as these creatures generate considerable waste due to their continuous feedings.

Keeping an eye on several water parameters is necessary in creating a beneficial habitat where your pets can live happily. They include pH levels, undetectable ammonia levels, calcium so they can maintain their bodies, alkalinity readings, and salinity values. Quality test kits are essential for monitoring your parameters.

I recommend using a reef specific salt with these animals as these types of salt will maintain stable parameters to maintain their bony plates. You will want to consider an auto top off system to maintain salinity and consider dosing your tank if you plan on maintaining hard corals.

Temperature Control

Having an appropriate water temperature is crucial for the health and contentment of your seahorses. Different species need different temperatures: Hippocampus erectus should be kept in a range between 68°F to 74°F, while seahorse species H. reidi, H. comes, and H. kuda thrive best with higher levels around 72°F to 74°F .

To ensure that you maintain ideal conditions within your home aquarium these aquatic creatures it may be necessary install fans or chillers as additional sources of cooling if things get too hot inside their environment. Your best way to keep them cool is to keep your home cool too, but hotter climate a chiller or fan is going to be needed to maintain the low temperatures.

Water Parameters And Filtration

Maintaining proper water parameters in a seahorse aquarium is critical for the health of your seafaring pets. Check regularly on pH, ammonia, calcium and alkalinity as well as salinity levels to ensure that your tank remains habitable.

Nitrates should be kept at or below 20 ppm in order to help avoid stress. To keep up with optimal water quality for these unique animals it’s beneficial to invest in an effective filtration system using sponges, filter floss and/or socks, which are excellent choices when looking into keeping their home clean & safe from excessive waste buildup within saltwater aquariums housing sea horses.

Diet And Nutrition

For your sea creatures to stay healthy, it is essential that they eat a varied and nutritious diet. Seahorses consume different types of food such as mysis shrimp, brine shrimp, and copepods for protein. Feeding them multiple times in one day ensures your seahorse gets the necessary nutrients needed for their wellbeing.

To provide additional nutrition you can offer fresh seafood like shrimps too. This will also make sure your pet enjoys its meals! The variety of foods consumed by these creatures keeps them contented while preventing any malnutrition issues from arising.

Hand feeding is recommended if you are comfortable doing it. You can hear the same sentiment from FAMA Magazine below:

Handfeeding sea horses has several important advantages for both the aquarist and his pampered pets. First of all, it breaks the sea horse’s dependency on live foods, allowing the hobbyist to offer them a wide assortment of nutritious foods that would otherwise have to be excluded from their diet. Unlike live foods and frozen fare, which are limited to prey that is small enough to be swallowed whole, the food that is used for handfeeding can be cut into convenient, bite-sized pieces.

Quarantine And Conditioning

When introducing newly acquired seahorses, even captive bred ones, to their permanent tank it is essential that a period of quarantine and conditioning first takes place. This practice helps them acclimate smoothly into the new environment as well as give them time to rebuild lost strength due to transportation stressors. Quarantine also gives pet owners an opportunity for detection and treatment of any health problems before placing in the display aquarium.

The recommended quarantining duration should be no less than 30 days where closely monitoring activities such feeding behaviors, identifying potential illness can take place beforehand, guaranteeing your seahorse’s health before transferring over to your display tank permanently.

Selecting Compatible Tank Mates

Trumpet Coral

When it comes to the safety and health of your seahorse, having compatible tank mates is essential. To ensure that no harm befalls them, you should make sure to stay away from fast-moving or aggressive fish which could cause distress in their environment. Here are some species I would recommend:

  • Small blennies
  • Clown Gobies, Eel Gobies
  • Dragonets and Scooters
  • Royal Gramma (medium risk)
  • Small cardinalfish (medium risk)
  • Flasher wrasses (medium risk)
  • Young clownfish (not compatible as adults)

Invertebrates And Coral Compatibility

When introducing invertebrates and corals to a seahorse aquarium, it is important to choose species that are compatible with the aquatic mammals. Shrimp and snails should be safe additions but clams or scallops could potentially cause harm. Seahorses can get along fine with most soft coral types such as:

Some Large Polyp Stony (LPS) varieties are compatible, but avoid any with large mouths or stinging abilities. Euphyllias would be examples of LPS corals that are not compatible with seahorses

SPS corals are difficult to keep with seahorses do due to the seahorses higher nurient level requirements and the fact that their hitching behavior will bother your SPS corals.

Breeding: Tips and Challenges

Breeding seahorses can be an incredibly rewarding experience, offering a unique opportunity to watch the male bear and hatch its eggs. It is important to keep in mind that there are various challenges involved such as maintaining adequate water conditions and supplying enough nourishment for their fry.

You can read an excerpt from TFH Magazine about breeding. I’ll include a link to their article so you can get more information about them as depth in breeding is outside of this blog post:

The fishes of the genus Hippocampus, commonly known as seahorses, are reported to frequently reproduce in captivity. Most of the literature is also optimistic about the viability of seahorse fry. However, my experiences with maintaining and reproducing several species of Hippocampus demonstrates that a labor-intensive effort is required to obtain a new generation of adult seahorses, and even then the final outcome is uncertain.

Health: Preventive Measures And Treatment

Having a healthy seahorse aquarium takes proactive steps to avert diseases and have the right medication in your medicine cabinet. Regular water changes, quarantining new arrivals, and keeping space from overcrowding will help minimize illness risks for tank dwellers.

As well as employing preventive measures, stocking up on medicines can allow you to react quickly when sickness develops. Here are some medications to stock up:

  • Seachem Kanaplex (Anti-bacterial)
  • Seachem Neoplex (some hobbyists recommend Neosporin, but I’ll stick to aquarium-related products) – Antibiotic
  • Seachem Metroplex – Anti Parasitic

Note that Copper and Chloroquine Phosphate will not work on Seahorses. For hard parasites like Ich your only options are malachite green combos like Kordon Rid Ich and API Super Ich Cure.
