Alestidae species Ladigesia roloffi comes from West Africa. A mid-water shoaler whose colour and courage arrive together, with the group. It swims in mid-water. Adults reach 2.3–3.4 cm. Shoaling; 8–10+ unlocks full colour and calm. Dark substrate, gentle light, big school — the three levers for this fish. Maintain 22–26 °C at pH 6–7. A solid choice for a well-planned community tank.
