Parosphromenus harveyi

Usually lacks red areas, but can still be confused with some locality forms in the bintan complex.

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.
