生物學特性     字彙 (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).

棲息於大的分離流動清澈的河，小的溪流, 流域溝渠與人造的池塘與圈圍水域。 (參考文獻 11225) 吃浮游動物，碎屑，較高等的植物與有時在魚的鱗片上。 形成配子為繁殖在乾季的時候及時發生在雨季的時候開始。 (參考文獻 12225) 繁殖可能是成功完成在繁殖場.(參考文獻 27188)
