Parosphromenus deissneri

The caudal fin is roughly triangular to diamond-shaped, with a prominent filament. Other licorice gouramis were often sold under this name.

Needs very soft, acidic water.

Social behaviour and territory

Does not form tight schools. Pairs can be used for breeding; groups need caves and cover. Watch nest guarding and subordinate fish.

Offer tiny, suitably sized live foods. Dry food is unreliably accepted; confirm the fish actually eat.
