Keep the water calm, with floating plants and tall stems for cover, and leave a little open water at the surface, because gouramis breathe air. A lid keeps the air above the water warm, which protects the labyrinth organ.

Behaviour and Tankmates

A calm, deliberate fish that explores with its long, thread-like pelvic fins and takes breaths of air from the surface.

Can be kept singly or in a small group. Males may squabble, so give them cover if you keep more than one.

Males can be territorial, especially when building a nest.

Usually suits a calm community of fish that are not too boisterous. Avoid fin nippers, which go for its long pelvic fins. It is likely to eat shrimp. Choose its tankmates with care.
