Peaceful mid-water shoaler; confidence comes in numbers
产地
南美洲
物种概述
From the waters of 南美洲 comes Copella arnoldi, a member of the family Lebiasinidae. A mid-water shoaler whose colour and courage arrive together, with the group. It lives on the bottom. Adults reach 3.2–4.6 cm. Groups of 8 minimum; more is visibly better. Dark substrate, gentle light, big school — the three levers for this fish. Maintain 25–29 °C at pH 6–8. Water quality and diet matter more than décor.
