Anabantoids · Intermediate care
Croaking gourami
Trichopsis vittata
Croaking gourami is rated intermediate here because of its adult size, water range and social needs. Use gentle surface movement, floating cover and a secure lid.

Is Croaking gourami a good aquarium fish?
Croaking gourami reaches about 6 cm as an adult, so plan around the adult fish rather than the juvenile size seen in shops. The suggested minimum of 15 US gallons assumes suitable filtration, open swimming space and routine maintenance.
Generally peaceful in a suitable community. Keep the recommended group of one fish or a compatible pair and avoid mixing it with tank mates that need a very different temperature, water chemistry or swimming level.
Water and aquarium setup
A stable temperature of 24–28°C and pH of 5.5–7.5 are the working ranges in the planner. Stability and clean, oxygenated water matter more than chasing a single target number.
Keep the surface calm enough for labyrinth-fish breathing, add floating cover and use a tight lid to reduce jumping and cold air exposure.
Diet
Small floating or slow-sinking pellets, frozen foods and occasional live foods.
Compatibility notes
Croaking gourami is generally workable in a community aquarium when the tank mates share its temperature range and social needs.
Use the Stocking & Bioload Planner to check a proposed community. Its estimated bioload value for one adult croaking gourami is 1.58 units; this is a planning heuristic, not a replacement for testing nitrate.
Common mistakes
- Planning around the shop size instead of the adult size.
- Adding a schooling fish in a group smaller than its social minimum.
- Ignoring the tank's length, floor area or lid because the gallon number looks adequate.
- Adding fish before the aquarium is cycled and ammonia and nitrite are consistently zero.
Care ranges are conservative summaries of commonly cited husbandry references. Individual fish, strains and local water can differ; monitor the aquarium and adjust the plan gradually.
