Parosphromenus allani

Tail patterns are less regular than in tweediei. Females and juveniles should not be identified by color pattern alone.

Needs extremely soft, acidic water.

Social behaviour and territory

Does not form tight schools. Pairs may be used for breeding; groups need caves and visual barriers. Watch nest defenders and subordinate fish.

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