14 Gourami Types: My Picks, the Dwarf Gourami Disease Warning, and What to Actually Buy

Last Updated: May 16, 2026

Not all gouramis are created equal. Some are peaceful centerpiece fish that thrive for a decade. Some will destroy everything in the tank. And one of the most popular species carries a viral disease in the majority of imported stock that kills it within a year.

The gourami you pick determines whether your community tank works or falls apart.

Here is what you actually need to know about 14 gourami species, including the disease warning nobody at the fish store tells you.

What Are Gouramis?

Gouramis belong to the Osphronemidae family and originate in South and Southeast Asia. Over 130 species exist, with a wide range represented in the aquarium trade. They come in every size from the tiny sparkling gourami at 1.5 inches (4 cm) to the giant gourami at over 24 inches (60 cm).

The defining feature is the labyrinth organ. Gouramis evolved in oxygen-poor, slow-moving water and developed the ability to breathe air directly from the surface. This is not optional behavior. It is how they survive. In a tank, this means the surface must always be accessible. Floating plants that block the entire surface are a real risk. So is a sealed lid without a gap.

Gouramis also have modified pelvic fins that extend into long, whisker-like feelers they use to sense their environment. Males use them to investigate territory and other fish. Watching a gourami probe the tank with its feelers is part of what makes them engaging to keep.

Most species are bubble nest builders. Males construct nests at the surface from bubbles coated in saliva, then guard the eggs and fry aggressively after spawning.

The Dwarf Gourami Iridovirus Problem

This needs its own section because most people never hear about it until their fish is already dying.

Dwarf gourami iridovirus (DGIV) is a megalocytivirus endemic in Southeast Asian fish farms, which is where essentially all dwarf gouramis in the hobby come from. Research published in aquatic disease journals has documented infection rates above 20 percent in imported shipments, and anecdotal reports from experienced hobbyists and retailers suggest the real rate is considerably higher.

The virus causes progressive immune system failure. Infected fish typically show color loss, swelling, lesions, and loss of appetite before dying. There is no treatment. The timeline from purchase to death is usually six months to a year, sometimes less.

This does not mean you cannot keep dwarf gouramis. It means you should buy from suppliers who source domestically or from reputable farms with disease management protocols, quarantine every dwarf gourami before adding it to a display tank, and have realistic expectations. A dwarf gourami that lives four to five years is a success. Many do not make it to two.

The honey gourami is the practical alternative. It does not carry DGIV at the same rate, it is equally peaceful and similarly sized, and it is genuinely harder in terms of water parameter tolerance. If you want a small, colorful gourami for a community tank, the honey gourami is the more reliable choice.

14 Best Gourami Types for Freshwater Aquariums

1. Honey Gourami

• Scientific Name: Trichogaster chuna
• Difficulty Level: Easy
• Temperament: Peaceful
• Adult Size: 2 inches (5 cm)
• Minimum Tank Size: 15 gallons (57 L)
• Temperature: 72-81°F (22-27°C)
• pH: 6.0-7.5

The honey gourami is my recommendation for anyone who wants a small, colorful gourami for a community tank. It is genuinely peaceful, hardy enough to handle beginner water parameter fluctuations, and does not carry the iridovirus risk that plagues standard dwarf gourami imports. Males develop a deep golden-orange color when in breeding condition. This is the gourami I would send someone home with first.

2. Sparkling Gourami

• Scientific Name: Trichopsis pumila
• Difficulty Level: Easy
• Temperament: Peaceful
• Adult Size: 1.5 inches (4 cm)
• Minimum Tank Size: 10 gallons (38 L)
• Temperature: 72-82°F (22-28°C)
• pH: 5.0-7.5

The sparkling gourami is genuinely stunning in a planted nano tank. The iridescent turquoise on the body and fins catches light in a way that surprises people who do not expect much from a 1.5-inch (4 cm) fish. They are peaceful but do not keep them with shrimp. Those feelers are not just for sensing; sparkling gouramis hunt small invertebrates actively.

3. Licorice Gourami

• Scientific Name: Parosphromenus deissneri
• Difficulty Level: Moderate (for beginners: difficult)
• Temperament: Peaceful
• Adult Size: 1.5 inches (4 cm)
• Minimum Tank Size: 5 gallons (19 L)
• Temperature: 72-82°F (22-28°C)
• pH: 3.0-6.5

The licorice gourami is one of the most beautiful fish in the hobby and one of the most demanding. It needs very soft, acidic water, live food daily (they reject flakes and pellets reliably), and a calm, species-appropriate setup. This is a specialist fish for experienced keepers who have a blackwater tank already running. It is not a beginner gourami despite its small size.

4. Pearl Gourami

• Scientific Name: Trichopodus leerii
• Difficulty Level: Easy
• Temperament: Peaceful
• Adult Size: 4.5 inches (11 cm)
• Minimum Tank Size: 30 gallons (114 L)
• Temperature: 75-86°F (24-30°C)
• pH: 5.5-8.0

The pearl gourami is the most underrated gourami in the hobby. It is peaceful, genuinely stunning with its intricate pearl spotting and red-orange breast on males, and hardy enough for a beginner with a properly established tank. This is the gourami I would recommend as a centerpiece fish in a community setup over any dwarf variety. Up to ten years of lifespan. Takes a range of foods. Does not cause trouble. There is very little downside.

5. Blue Gourami (Three Spot)

• Scientific Name: Trichopodus trichopterus
• Difficulty Level: Easy
• Temperament: Semi-aggressive
• Adult Size: 5-6 inches (13-15 cm)
• Minimum Tank Size: 35 gallons (132 L)
• Temperature: 75-86°F (24-30°C)
• pH: 5.5-8.5

The blue gourami is a color variant of the three-spot gourami, along with gold and opaline variants. Hardy and easy to keep, but males are semi-aggressive, especially toward each other and other labyrinth fish. One male per tank. The blue color and size make it a visible, active tank presence, but pair it with fish that can hold their own. Timid fish do not do well as tankmates.

6. Kissing Gourami

• Scientific Name: Helostoma temminkii
• Difficulty Level: Moderate
• Temperament: Semi-aggressive
• Adult Size: 8-10 inches (20-25 cm)
• Minimum Tank Size: 75 gallons (284 L)
• Temperature: 71-86°F (22-30°C)
• pH: 6.0-8.0

The “kissing” behavior is not affection. It is a dominance display. Two kissing gouramis pressing their mouths together are establishing hierarchy, not bonding. This is important context because people buy two and expect them to be friends. They may or may not get along. At 8 to 10 inches (20-25 cm) they also need considerably more space than their typical retail tank size suggests, and they will eat soft-leaved plants.

7. Giant Gourami

• Scientific Name: Osphronemus goramy
• Difficulty Level: Moderate (tank size is the barrier)
• Temperament: Peaceful (but will eat small fish)
• Adult Size: 20-28 inches (51-71 cm), up to 18 inches (46 cm) in captivity typically
• Minimum Tank Size: 200 gallons (757 L)
• Temperature: 68-86°F (20-30°C)
• pH: 6.5-8.0

Giant gouramis are sold as juveniles at 3 to 4 inches (8-10 cm) and can fool people into thinking they are a reasonable aquarium fish. They are not reasonable for most hobbyists. They grow fast, they live 20 years, and they ultimately need a tank that most people do not have space or budget for. If you have that space and that commitment, they are genuinely personable fish that behave more like a large wet dog than a display animal.

8. Powder Blue Dwarf Gourami

• Scientific Name: Trichogaster lalius
• Difficulty Level: Moderate (DGIV risk elevates this)
• Temperament: Peaceful
• Adult Size: 2.4-3 inches (6-8 cm)
• Minimum Tank Size: 15 gallons (57 L)
• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5

A color variant of the standard dwarf gourami with the same DGIV risk. Beautiful electric blue color with red accents. Males can be territorial toward each other. The DGIV caveat applies: buy from a reputable source, quarantine before adding to a display tank, and understand the shortened lifespan risk. The honey gourami is the safer alternative for most keepers.

9. Snakeskin Gourami

• Scientific Name: Trichopodus pectoralis
• Difficulty Level: Easy
• Temperament: Peaceful
• Adult Size: 8-12 inches (20-30 cm)
• Minimum Tank Size: 30 gallons (114 L) as juveniles; needs 55+ gallons (208+ L) as adults
• Temperature: 72-86°F (22-30°C)
• pH: 5.8-8.5

The snakeskin gourami is possibly the most peaceful gourami species you can buy. The downside is that it grows to 8 to 12 inches (20-30 cm) and does not stay small. The 30-gallon (114 L) listed minimum is for juveniles. Adults need considerably more space. May eat smaller fish and occasionally nibble on plants. Easy to care for otherwise.

10. Gold Gourami

• Scientific Name: Trichopodus trichopterus
• Difficulty Level: Easy
• Temperament: Semi-aggressive
• Adult Size: 5-6 inches (13-15 cm)
• Minimum Tank Size: 35 gallons (132 L)
• Temperature: 75-86°F (24-30°C)
• pH: 5.5-8.5

Same species as the blue gourami, different color variant. Rich golden-yellow with marbling on fins and body. Same care requirements, same semi-aggressive male behavior. If you want the three-spot gourami’s hardiness with different aesthetics, the gold variant is a solid choice.

11. Moonlight Gourami

• Scientific Name: Trichogaster microlepis
• Difficulty Level: Moderate
• Temperament: Peaceful
• Adult Size: 6 inches (15 cm)
• Minimum Tank Size: 35 gallons (132 L)
• Temperature: 77-86°F (25-30°C)
• pH: 6.0-7.5

The moonlight gourami has less obvious color than most species on this list, but the silver-blue sheen at certain angles and the bright red feelers on males more than compensate. It does great in community tanks with other peaceful species. Pairs well with other peaceful gouramis as long as there is only one male per species.

12. Sunset Gourami

• Scientific Name: Trichogaster labiosa
• Difficulty Level: Easy
• Temperament: Peaceful
• Adult Size: 4 inches (10 cm)
• Minimum Tank Size: 15 gallons (57 L)
• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5

The sunset gourami is one of the best community tank choices on this list. Golden orange coloration, peaceful toward tankmates and their own kind, and no inter-male aggression problems at the same scale as the dwarf gourami variants. Sometimes confused with the honey gourami sunset color form, so confirm labeling at the store.

13. Flame Dwarf Gourami

• Scientific Name: Trichogaster lalius
• Difficulty Level: Moderate (DGIV risk)
• Temperament: Peaceful
• Adult Size: 2.4-3 inches (6-8 cm)
• Minimum Tank Size: 15 gallons (57 L)
• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5

The flame dwarf gourami is a color variant of the dwarf gourami with solid golden-orange body and electric blue dorsal fin. Spectacular looking fish. Same DGIV risk as all dwarf gourami variants imported from Southeast Asia. If you buy one, source carefully and quarantine.

14. Blue Paradise Gourami

• Scientific Name: Macropodus opercularis
• Difficulty Level: Moderate
• Temperament: Semi-aggressive
• Adult Size: 3 inches (8 cm)
• Minimum Tank Size: 20 gallons (76 L)
• Temperature: 50-71°F (10-22°C)
• pH: 6.0-8.0

The blue paradise gourami’s tolerance for cooler water (down to 50°F/10°C) makes it unique in this group. It does not need a heater in most room-temperature homes. Aggressive around breeding, and males fight. Keep one male with two or more females. Do not add other labyrinth fish to a tank with a breeding male paradise fish.

Tank Setup

Tank size requirements vary enormously across this group. A sparkling gourami in 10 gallons (38 L) is well-housed. A giant gourami in that same 10 gallons is a welfare problem. Know the adult size of your chosen species before buying the tank.

Gouramis evolved in slow-moving, heavily vegetated water. Strong current stresses them. Aim for gentle filtration. A sponge filter works well for smaller species. For larger tanks, aim the power filter outlet at hardscape to break up the current. A spray bar attachment on a canister filter is the cleanest solution for bigger setups.

Plants are important. Gouramis feel more secure with plant cover and will show better color in a well-planted tank than in a bare or minimally-decorated setup. Good choices: java fern, anubias, cryptocoryne, vallisneria. Floating plants work well too, but leave significant open surface area for air breathing.

The surface access point bears repeating. If a gourami cannot reach the surface to breathe, it drowns. This is not a slow process. Make sure your lid has a gap, especially where the water sits close to the surface in heavily planted tanks.

Behavior and Feeding

Most gouramis accept a wide range of foods. Flake or pellet food as a base, supplemented with frozen and live foods, works for most species. More specialized species like the licorice gourami and chocolate gourami require live or frozen food exclusively, and they are not the fish to start with.

Males are territorial toward other males of the same species. This is not a rule you can work around with clever tank design in smaller tanks. One male per species per tank in anything under 55 gallons (208 L). Larger tanks with heavy planting and many sight breaks can sometimes accommodate two males of the same species, but this requires close monitoring.

Gouramis use their feelers constantly. Watching a gourami investigate new decorations, test water movement, or probe tank mates is part of the appeal. They are interactive fish that notice their environment in ways many community species do not.

Breeding

Most gouramis are bubble nest builders and reasonably easy to breed once conditioned. A shallow breeding tank of 6 to 8 inches (15-20 cm) depth, slow filtration from a sponge filter, and water in the low 80s°F (around 28°C) is the standard setup. Feed live and frozen foods to condition the pair before attempting to spawn.

The male builds the bubble nest and guards it obsessively after spawning. Remove the female at this point because the male will become aggressive. Once the fry are free-swimming (usually 3 to 4 days after hatching), the male is typically removed as well, or the fry risk being eaten.

Feed fry infusoria or commercially available liquid fry food initially, transitioning to baby brine shrimp as they grow.

Tank Mates

Peaceful gouramis like the honey, pearl, sparkling, and moonlight species pair well with smaller schooling fish, corydoras, otocinclus, and other peaceful community species. Avoid fin-nippers. The long feeler fins are an obvious target and tiger barbs in particular will shred them.

Semi-aggressive species like the blue, gold, kissing, and paradise fish are better paired with fish that are similarly sized and not easily intimidated. Danios, barbs that are not notorious fin-nippers, and larger tetras work well.

Do not mix multiple labyrinth fish species in smaller tanks. Male bettas and male gouramis in the same tank is a common mistake. Both species see the other as competition, and the outcome is predictable.

FAQs

Closing Thoughts

Gouramis are some of the most varied and rewarding freshwater fish you can keep. The pearl gourami is genuinely one of the hobby’s underrated gems. The honey gourami is the practical beginner choice that outlasts the more commonly purchased dwarf gourami at most fish stores.

If you take nothing else from this article, take the DGIV warning seriously. The dwarf gourami iridovirus is real, it is common, and it is the reason so many of these fish die within a year of purchase. Shop from better sources, quarantine your fish, or choose a species that does not carry the same risk.

Where to Buy Gouramis

Gouramis are widely available, but quality varies significantly by source. For disease-reduced stock and healthier fish overall, online specialty retailers are often more reliable than chain fish stores that order from mass importers.
