物种概述

Nannostomus harrisoni, a member of the family Lebiasinidae, is native to 南美洲. Its colours are honest signalling: pale, scattered fish are telling you something is wrong. It lives on the bottom. Adults reach 3.4–5 cm. Groups of 8 minimum; more is visibly better. Keep a proper school, dim the glare, and feed small foods several times a day. Maintain 24–28 °C at pH 5.5–7. A rewarding species for the aquarist who reads before buying.
