The honey gourami (Trichogaster chuna, sometimes classified as Trichopodus chuna) is one of the calmest, most colorful members of the gourami family, and a favorite recommendation for aquarists who want gourami personality without gourami aggression.
Honey gourami care is genuinely beginner-friendly: this labyrinth fish tops out around 2 inches, tolerates a wide range of established water parameters, and needs only a well-planted 10-gallon-plus tank with gentle flow and reachable surface access for breathing air. Its peaceful temperament also makes it one of the easiest gouramis to house in a community setting.
Key takeaways:
- Honey gouramis stay small, typically 2 to 2.2 inches (5-5.5 cm) at full adult size.
- A single pair needs at least 10 gallons, with roughly 5 gallons added per additional fish.
- They prefer warm, soft, slightly acidic water: 75-82°F and a pH of 6.0-7.5.
- As labyrinth fish, they must reach the surface to gulp air, so surface access can never be blocked off.
- Males display a striking honey-orange breeding color and build floating bubble nests, unlike females, which stay pale brown or yellow.
How Big Do Honey Gouramis Get, and Are They Beginner-Friendly?
Honey gouramis are one of the smallest gourami species kept in the hobby. Wikipedia lists a maximum length of about 5.5 cm (2.2 inches), and most aquarium specimens stay in the 2 to 2.2-inch range for their whole lives. With stable water quality, honey gouramis typically live 3 to 5 years, occasionally longer.
This modest size, combined with a genuinely peaceful temperament, is exactly what makes honey gourami care beginner-friendly in a way that many other anabantoids are not. Larger relatives like the three-spot or pearl gourami can become territorial or even aggressive as they mature, but honey gouramis rarely show that behavior even in a community tank. A 10-gallon planted setup with stable parameters is genuinely enough to keep this species successfully, which is not something that can be said for most of its larger cousins.
What Tank Size and Setup Does a Honey Gourami Need?
A single pair of honey gouramis can be kept in a tank as small as 10 gallons, per Seriously Fish's recommended minimum footprint of 60 x 30 cm, though a slightly larger tank in the 15-20 gallon range gives a small group more stable social dynamics. As a rule of thumb, budget roughly 5 gallons for each additional fish once the base pair is established.
Honey gouramis come from calm, thickly vegetated waters in India and Bangladesh, and the tank should mimic that: dense planting with Java fern, Anubias, or Cryptocoryne, some floating cover like Salvinia to soften the lighting, and only gentle water flow, since these are not fish adapted to strong current. An air-powered sponge filter is often a better fit than a canister filter's high-output spray bar. As of 2026, FishBase confirms the species' native distribution remains limited to freshwater habitats across India and Bangladesh, with no established use in commercial fisheries outside the aquarium trade.
For anyone specifically working with a small footprint, honey gourami pairs are consistently one of the better choices among the best fish for a 10-gallon tank.
What Water Parameters Do Honey Gouramis Need?
| Parameter | Recommended Range |
|---|---|
| Temperature | 75-82°F (24-28°C) |
| pH | 6.0-7.5 |
| General hardness | 4-12 dGH |
| Ammonia/Nitrite | 0 ppm |
| Nitrate | Under 20-30 ppm |
Honey gouramis tolerate a fairly wide range of established water chemistry, but they do best in soft, slightly acidic to neutral conditions that mirror their native, poorly mineralized habitat. As with most labyrinth fish, keeping ammonia and nitrite at zero matters more than chasing an exact pH number. University of Florida IFAS Extension research on aquatic ammonia found that the un-ionized form becomes measurably toxic to fish above roughly 0.05 mg/L, well below levels that are visible without a test kit.
New tanks should be fully cycled before stocking, and once established, regular partial water changes every one to two weeks keep nitrate from creeping up between tests.
What Do Honey Gouramis Eat?
Honey gouramis are omnivores that lean toward small live and frozen foods in the wild, preying on tiny invertebrates in their native rivers and flooded fields. In the aquarium, a base diet of high-quality micro pellets or flakes formulated for small fish works well, supplemented two or three times a week with daphnia, baby brine shrimp, or bloodworms to maintain color and condition. For a broader look at feeding this family of fish, see what gouramis eat, since the same general principles apply across most gourami species.
Because honey gouramis are slow, deliberate feeders compared to faster tank mates, food that sinks or disperses slowly gives them a fair chance to eat before more active fish clear it out.
Why Do Honey Gouramis Build Bubble Nests, and How Do You Tell Males From Females?
Honey gouramis have a labyrinth organ, an accessory breathing structure shared by all anabantoids, that lets them gulp atmospheric air directly at the water's surface in addition to breathing through their gills. This is a genuine, easily observed behavior in a healthy tank: watch a honey gourami for a few minutes and it will periodically rise to the surface and take a visible gulp of air, which is normal and expected rather than a sign of an oxygen problem in the water. Because of this, honey gouramis need reliable, unobstructed access to the surface; dense floating plant cover is fine, but the tank should never be sealed in a way that blocks air access entirely.
This same labyrinth adaptation is closely tied to the species' breeding behavior. Males build a bubble nest at the surface, a cluster of mucus-coated bubbles, sometimes reinforced with bits of floating plant material, and use it to hold fertilized eggs after spawning. For a full breakdown of this behavior across gourami species, see gourami bubble nest building. In honey gouramis specifically, eggs hatch in roughly 24 to 36 hours, and the male tends the nest and fry until they become free-swimming a day or two later.
Bubble-nest building is also the easiest way to sex this species, since a male in breeding condition is unmistakable. Outside of breeding condition, males and females look fairly similar and can be harder to distinguish. Females stay a light yellowish-brown with a faint midlateral stripe and grow noticeably deeper-bodied than males as they mature. Males, by contrast, develop a dramatic honey-orange to reddish body color with a dark blue-black throat and underside once they're ready to breed or display for a female, and their dorsal and anal fins grow longer and more pointed than the female's rounded fins. This color change is triggered by breeding readiness rather than being a constant trait, so a young or unconditioned male can look almost identical to a female until he matures and starts displaying.
What Are Good Tank Mates for Honey Gouramis?
Honey gouramis are peaceful and slow-moving, which means the biggest compatibility risk isn't aggression from the honey gourami. It's boisterous tank mates outcompeting them for food or intimidating them into hiding. Good tank mates share that same calm, unhurried temperament:
- Small tetras and rasboras, such as harlequin rasboras or ember tetras, that won't outcompete a slow feeder
- Sparkling gouramis, another similarly small, peaceful anabantoid species
- Cherry or amano shrimp, since adult honey gouramis are too small and peaceful to bother them
- Small, peaceful corydoras that occupy the bottom of the tank rather than competing at the surface
Avoid pairing honey gouramis with large, fast, or fin-nipping fish, and avoid keeping multiple male honey gouramis in a tight space, since males can become territorial toward each other even though the species overall is considered peaceful.
Frequently Asked Questions
Are honey gouramis beginner-friendly?
Yes, honey gouramis are considered one of the most beginner-friendly gourami species. They stay small at around 2 inches, tolerate a fairly wide range of established water parameters, and are far less territorial than larger gouramis like the three-spot or pearl gourami. A 10-gallon planted tank with gentle flow and stable water quality is enough to keep a pair successfully.
How big of a tank does a honey gourami need?
A pair of honey gouramis can be kept in a tank as small as 10 gallons, with roughly 5 additional gallons budgeted for each extra fish. A well-planted tank with gentle water flow and floating cover suits the species better than a large, open, high-flow aquarium, since honey gouramis come from calm, vegetated waters.
Why does my honey gourami keep swimming to the surface?
Honey gouramis are labyrinth fish, meaning they have an accessory breathing organ that lets them gulp air directly at the water's surface in addition to breathing through their gills. Periodically rising to gulp air is completely normal behavior, not a sign of poor water quality, but the tank must always allow clear access to the surface for this to happen safely.
How can you tell a male honey gourami from a female?
Once a male honey gourami is in breeding condition, he develops a striking honey-orange to reddish body with a dark throat and longer, more pointed fins. Females stay a plainer light brown to yellow with a faint stripe and a rounder body shape. Outside of breeding condition, young or uncolored males can be harder to distinguish from females.
What is a honey gourami's bubble nest for?
A bubble nest is a cluster of mucus-coated bubbles that a male honey gourami builds at the water's surface, sometimes reinforced with bits of floating plant material. After spawning, the male places fertilized eggs into the nest and guards them until they hatch, typically within 24 to 36 hours, tending the fry for another day or two after that.
What fish make good tank mates for honey gouramis?
Small, peaceful, similarly-paced fish make the best tank mates for honey gouramis: harlequin rasboras, small tetras, sparkling gouramis, shrimp, and peaceful corydoras all work well. Fast, boisterous, or fin-nipping fish should be avoided, since they can outcompete a honey gourami for food or intimidate it into hiding rather than attacking it outright.
