This species has small silvery scales; small mouth, and with a relatively large adipose fin (Ref. 10615).
这种有小的银色鳞片; 小的嘴, 而且具有一个相当大的脂鳍.(参考文献 10615)
A mud-eating fish, feeding on the organic matter that forms on submerged stones and higher plants (aufwuchs). Matures sexually under normal rain patterns with first spawning occurring during the first year. Individuals of approximately 16 cm total length have reached sexual maturity. A typical migratory fish, with periodical and prolific reproduction. It does not spawn in captivity nor does it react satisfactorily to the common induced spawning techniques used successfully with other species (Ref. 10615).
一个吃泥的鱼, 吃在水下的石头与较高等的植物 (附着生物) 上形成的有机物。 性成熟在正常的雨图案下面具有第一个产卵在第一个年期间出现。 大约 16 公分全长的个体已经达成性成熟。 一个典型的回游鱼, 与周期与多产的繁殖。 它不会产卵于繁殖场中它也不满意地反应到普遍引诱产卵被成功使用于其他的种的技术.(参考文献 10615)
