Honey gouramis (Trichogaster chuna) are small, usually peaceful labyrinth fish that suit a quiet planted aquarium. They reach roughly 5–5.5 cm, but small size does not remove the need for space, stable water and protection from harassment.
Confirm the species before buying
Honey gouramis and dwarf gouramis are different species. Shop labels such as “red honey” or “sunset” are also unreliable identifiers: the larger thick-lipped gourami, Trichogaster labiosa, has a sunset strain too. Ask for the scientific name and expected adult size rather than treating every orange gourami as a honey.
Color changes with sex, strain and condition. A natural-form breeding male develops dark coloration beneath the head and along the front underside; females are generally less colorful. Color alone is less useful for sexing ornamental strains and young fish.
Space, cover and surface access
Seriously Fish lists a 60 × 30 cm starting footprint. A 20-gallon long aquarium offers more flexibility for a small group and carefully limited companions. Dense cover helps fish avoid one another, but watch for a dominant fish repeatedly excluding another from food or shelter. Do not calculate stocking using an inch-per-gallon rule.
Plant the margins, provide floating cover and keep some surface open for breathing. Use gentle circulation and a secure cover with an air gap. A sponge filter can provide suitable filtration when sized and maintained for the stocking. Air breathing does not make polluted water safe.
Water and everyday feeding
The species reference gives 22–27°C, pH 6.0–7.5 and 2–15 dGH. Choose stable conditions within an appropriate overlap for all inhabitants. Test your source water before deciding whether any adjustment is needed; do not chase an acidic reading with repeated chemical additions.
Cycle the aquarium before stocking and keep ammonia and nitrite undetectable. Quarantine new arrivals and investigate abnormal breathing, appetite loss or visible lesions promptly. Moving one visibly sick fish does not automatically remove an infectious organism from the original aquarium.
Feed appropriately sized complete flakes or granules, with small frozen or live invertebrates for variety. Confirm that timid individuals actually get food. Nutritional adequacy depends on the complete formula, not a blanket rule against every plant-derived ingredient.
Companions and aggression
Choose quiet species with compatible temperature and water chemistry, such as a properly housed group of harlequin rasboras. Avoid fin nippers, large predators and fish that monopolize feeding. Fry and young shrimp may be eaten.
Mixing with a betta is a risky default, especially in a small aquarium. Choosing a different-colored betta does not ensure compatibility. Gouramis can also chase one another, particularly around a nest; keep a separation option available.
Breeding needs preparation
The male builds a bubble nest and guards it after spawning. Provide a separate, covered breeding setup with gentle filtration and refuge for the female. Remove her if the male drives her away, and separate the male when parental care ends rather than assuming either parent will never eat young.
Prepare suitable microscopic fry food before spawning. Newly free-swimming fry are too small for ordinary crushed food or an immediate switch to brine shrimp. Keep water changes gentle and temperature-matched while increasing food size as they grow.
