Croaking gourami care
Trichopsis vittata · Ponds, canals and rice paddies of Southeast Asia

In a 15 gallon
24¼ × 12½ × 12¾ in outsideHow to keep croaking gouramis
The croaking gourami is a small, shy labyrinth fish named for its sound: when males display they croak by flicking their pectoral fins, loud enough to hear outside the tank. Keep three or more in a planted 15 gallon or larger tank with floating plants, a dark substrate and small, peaceful tankmates, in a quiet room: it is very sensitive to noise.
Diet: Micropredator: small frozen and live foods, crushed flakes, micro pellets. Fish food types compared · how often to feed.
Where they swim: Top of the tank.

Tests ammonia, nitrite, nitrate and pH, the readings that matter most before and after adding croaking gouramis.
Seachem Prime 100 mL
Removes chlorine and chloramine from tap water at every water change.
Fluval Edge Thermometer
Shows the water temperature at a glance, so you know it stays within 72 to 82 °F.

Common croaking gourami problems
- Cold air over the water can harm the labyrinth organ it breathes with: keep a lid on and the room warm.
- Bare tanks stress it; give it plants, floating cover and places to hide.
- Male bettas go after it: don’t keep the two together.
Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
