種の概要

Hyphessobrycon erythrostigma is a Characidae from 南美洲及菲律宾. Its colours are honest signalling: pale, scattered fish are telling you something is wrong. It lives on the bottom. Adults reach 4.6–6.7 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 23–28 °C at pH 5.6–7.2. Best suited to a keeper who can match its natural water.
