Overview
Keep a group of six or more in a 60 litre blackwater tank at 26 to 30 C with very soft, acidic water at pH 4.0 to 6.5, leaf litter, and tannins. Feed small live and frozen foods such as baby brine shrimp, daphnia, grindal worm, and micro worm, since it can be a picky micropredator. It is peaceful and shy and needs its own calm species tank or the gentlest of nano tankmates. Stable soft water and a tight lid to trap a warm humid layer above the surface are important.
In the wild
Lives in shaded blackwater peat swamps and streams that are very soft, acidic, and stained dark with tannins. The water is warm and mineral-poor, with pH often well below 6. It stays among leaf litter, roots, and submerged plants in dim light. These peat swamp habitats are being lost to drainage and clearing.
Good to know
Sphaerichthys selatanensis was described by Vierke in 1979 and belongs to the family Osphronemidae. Unusually for a labyrinth fish, it is a maternal mouthbrooder, meaning the female carries and broods the eggs and fry. It is a small chocolate gourami staying under 5 cm with pale crossbands on a dark body.
Did you know
The female broods the eggs in her mouth, a reversal of the male mouthbrooding seen in some other chocolate gouramis.
