Honey Gourami

Trichogaster chuna

The Honey Gourami (*Trichogaster chuna*) is probably the perfect dwarf labyrinth fish for domestic fishkeeping. Often unfairly snubbed due to its faded and colorless juvenile livery, the mature male that settles in the tank reveals his true nature: the body lights up with a dazzling golden-honey or intense amber color, in sharp and extraordinary contrast with a velvety black mask covering the entire belly, from the face down to the anal fin, while the dorsal fin is edged in lemon yellow. Unlike the infamous and very fragile Dwarf Gourami (*T. lalius*), the Honey Gourami is incredibly resistant to disease, peaceful to the point of shyness and reaches tiny dimensions (4-5 cm / 2 inches), making it the undisputed star for freshwater nano-aquariums.

Species description

Geographical Origin and Habitat: Immensely charming and delicate, the Honey Gourami inhabits the sprawling, sun-baked alluvial floodplains of northern India and Bangladesh, heavily localized within the massive Brahmaputra and Ganges river basins. It exhibits a strict biological preference for exceedingly sluggish, stagnant, or purely seasonal bodies of water: isolated marshes, murky ponds, deeply shaded oxbow lakes, and agricultural irrigation ditches totally choked out by a massive, impenetrable canopy of aquatic surface vegetation.
Taxonomy and Morphology: A highly peaceful, dwarf anabantoid of the Osphronemidae family that physically embodies grace. Exceedingly small in stature (barely topping out at 4.5 - 5 cm / 1.7 - 2 inches), it boasts a heavily compressed, elongated oval-shaped body. Characteristic of all true *Trichogaster* species, its ventral (pelvic) fins are dramatically mutated into two phenomenally long, whip-like "tactile feelers". These incredible, highly sensitive appendages act as biological sonar: the fish uses them constantly to meticulously touch, probe, and inspect rocks, plants, food, and even other tankmates, navigating safely through the pitch-black, turbid waters of its native swamps.
Social Behavior: Painfully docile, utterly harmless, and highly vulnerable. It is the absolute antithesis of its psychotically aggressive Betta cousins. It thrives beautifully in peaceful pairs or loose, gentle shoals. While breeding males may exhibit a sudden, comical burst of bravado—engaging in tiny, harmless territorial pushing matches—they are fundamentally incapable of inflicting any real damage. They hover with extreme, deliberate slowness and grace. They are immensely timid: if housed in harsh, barren, overly bright tanks lacking plant cover, they will suffer instant color loss due to shock, hiding shivering behind the filter intake for weeks.
Coloration and Sexual Dimorphism: The most radiant, saturated expression of pure gold in the hobby. The wild-type coloration (from which the "Honey" moniker stems) features abyssal sexual dimorphism. **Incredibly Distinct Dimorphism:** Females are visually unremarkable and dull, sporting a washed-out, greyish-brown canvas slashed by a thick, fuzzy, muddy-brown horizontal stripe down the flank. Males in breeding condition or showing dominance undergo a mind-bending, shocking metamorphosis: the entire body explodes into a blinding, vivid honey-gold/fiery-orange, severely contrasted by an intimidating, pitch-black (or dark inky-blue) mask that completely swallows his face, throat, and belly, heavily rimmed by an electric lemon-yellow dorsal stripe.

Care, breeding and tankmates

Aquarium Setup: Because it is a dwarf, clumsy, and slow swimmer, it is perfectly suited for smaller footprints (50-60 liters / 15 Gallons for a pair or trio). It harbors a visceral, biological hatred for heavy water flow: blasting hang-on-back filters or powerheads will exhaust and terrify them into a corner. The aquascape is a matter of life or death: you MUST provide a massive, impenetrable jungle of tall stem plants (Vallisneria) and a sprawling roof of thick floating plants (Water Lettuce, Salvinia) to completely block harsh LED lighting (which terrifies them) and to provide an anchor for their bubble nests. A sealed glass lid is strictly mandatory to protect the delicate, hot, humid air above the water required for their labyrinth lung function.
Diet and Feeding: An opportunistic insectivorous micro-predator plagued by an astoundingly tiny, restrictive mouth. It is an excruciatingly slow, hesitant, and polite eater, often staring at its food for seconds before striking. You must exclusively feed highly pulverized, premium micro-flakes or dust-like micro-pellets. To successfully unlock the male's spectacular "honey and black" breeding mask and fuel their immune system, it is mandatory to aggressively supplement with tiny live or frozen offerings: baby brine shrimp (nauplii), daphnia, grindal worms, and chopped bloodworms. It will completely ignore or spit out any chunk of meat that is too large for its tiny jaw to swallow.
Water Quality: Generally robust, but highly susceptible to chilling thermal shock. They demand true tropical waters spanning from mild to decidedly hot: 24-28°C (75-82°F) is optimal. They strongly prefer soft, slightly acidic to neutral chemistry (pH 6.5 - 7.5, GH 5-15). While pure, tannin-stained "blackwater" is not strictly required, they utterly despise sterile, brightly lit, hospital-like tanks devoid of protective shadows. Highly sensitive to heavy nitrate spikes and bacterial loads; perform gentle, routine water changes taking care not to violently crash the temperature.
Compatibility and Cohabitation: The absolute gold standard of fragile, peaceful tankmates. Phenomenal for carefully curated community tanks. NEVER house them with aggressive Cichlids, massively hyperactive shoaling fish (Zebra Danios, large Tetras, Barbs), or malicious "Fin-Nippers" which will ruthlessly target, bite off, and amputate the Gourami's long, delicate tactile pelvic feelers, sparking severe pain and lethal bacterial rot. The perfect, harmonious tankmates include gentle nano-fish: Dwarf Rasboras, Corydoras, Kuhli Loaches, Otocinclus, and ornamental shrimp (though a careless baby shrimp might occasionally be slurped up by a hungry gourami).
Aquarium Breeding: Spectacular yet architecturally fragile. The male claims a tiny, dark territory beneath a broad leaf or within the thickest mat of floating plants, meticulously spitting a tiny, often disorganized and fragile bubble nest. The classic labyrinth nuptial embrace and fertilization occur directly beneath the foam (with the buoyant eggs floating upward). Once fertilization completes, the tiny, peaceful "honey" male inexplicably transforms into a comical, pint-sized dictator: he will aggressively headbutt and drive away absolutely any fish (including his mate) that breaches his microscopic territory for the next three days, fiercely guarding the invisible fry.
Risks and Diseases: 1. Inhibitory Starvation (The Coward's Death): If housed in highly unbalanced community tanks alongside greedy, explosive eaters (like Tetras), the fast fish will completely devour all the food before the slow, hesitating Honey Gourami even realizes it's mealtime, resulting in a slow, heartbreaking death by malnutrition (evident by a sunken, knife-thin belly). 2. Tactile Feeler Amputation (Fin Nipping): Aggressive tankmates will sever their vital pelvic whips, leading to lethal infections. 3. High Susceptibility to Velvet (Oodinium/Gold Dust disease) if their immune system is crushed by aging, cold water.

Fish profile

Temperament
Semi-aggressive
Known for its exceptionally calm demeanor, The Honey gourami is an ideal candidate for a relaxed community aquarium. They rarely bother other fish and often retreat to safety rather than engage in any form of conflict. Their gentle nature means they can easily be outcompeted for food by faster, more boisterous species.
Diet
Omnivore
In the wild, The Honey gourami is an opportunistic omnivore that consumes a wide variety of plant and animal matter. In captivity, they will readily accept high-quality flakes, pellets, and frozen foods like bloodworms and brine shrimp. Supplementing their diet with blanched vegetables or spirulina-based foods will ensure optimal health and coloration.
Sex ratio
Harem
This species exhibits distinct sexual dimorphism, making it relatively easy to distinguish males from females once they reach maturity. Males typically display much more vibrant colors and possess longer, more pointed dorsal and anal fins compared to the females. It is often recommended to keep one male with multiple females to prevent the male from excessively harassing a single female during courtship.
Feeding frequency
Twice daily
To maintain optimal digestion, The Honey gourami should be fed small meals once or twice a day. It is important to only offer as much food as they can consume entirely within two to three minutes. Overfeeding can lead to severe water quality issues and potentially fatal digestive blockages.
Bioload
Low
The Honey gourami produces a relatively low biological load due to its small size and efficient metabolism. However, maintaining excellent water quality through regular maintenance is still fundamentally necessary. A well-established biological filter will easily handle the minimal waste produced by a group of these fish.
Flow
Stagnant
The Honey gourami naturally inhabits slow-moving or stagnant waters, such as swamps, rice paddies, and densely vegetated ponds. They strongly prefer an aquarium with very gentle water circulation, as strong currents will cause them significant stress and exhaustion. Using a sponge filter or baffling the output of a power filter is highly recommended.
Jump risk
No
Reproduction
Oviparous
During reproduction, the male of The Honey gourami constructs a complex bubble nest at the water's surface, often incorporating floating plant material. After a delicate courtship embrace, the female releases eggs which the male meticulously collects and places into the nest. The male then fiercely guards the nest and fry until they are free-swimming, at which point he should be removed to prevent him from eating them.
Compatibility & tankmates
Community
This species is generally very peaceful and makes an excellent addition to a community aquarium. They get along perfectly with other similarly sized, non-aggressive species that share similar water requirements. It is best to avoid keeping them with overly boisterous or large fin-nipping tank mates that might cause them stress.
Tank level
Top/Middle
You will typically find The Honey gourami swimming in the upper and middle regions of the aquarium. They occasionally venture to the bottom to forage but prefer the open swimming space and cover provided by tall plants in the upper layers. Providing a layout with plenty of vertical structure helps them feel most at home.
