Characidae species Hemigrammus ocellifer comes from 南美洲及菲律宾. A mid-water shoaler whose colour and courage arrive together, with the group. It lives on the bottom. Adults reach 3.7–5.4 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 6–8. A rewarding species for the aquarist who reads before buying.
