生物学特性     字汇 (例如 epibenthic)

Inhabits large free flowing clear rivers, small streams, drainage ditches and artificial ponds and impoundments (Ref. 11225). Feeds on zooplankton, detritus, higher plants and sometimes on the scales of fish. Gametogenesis takes place during the dry season in time for reproduction to begin during the rainy season (Ref. 12225). Reproduction could be carried out in captivity (Ref. 27188).

栖息于大的分离流动清澈的河，小的溪流, 流域沟渠与人造的池塘与圈围水域。 (参考文献 11225) 吃浮游动物，碎屑，较高等的植物与有时在鱼的鳞片上。 形成配子为繁殖在乾季的时候及时发生在雨季的时候开始。 (参考文献 12225) 繁殖可能是成功完成在繁殖场.(参考文献 27188)
