生物学特性     字汇 (例如 epibenthic)

Lives in peats and bog wetlands (Ref. 57235). Occurs in marshes, swamps and ponds with dense growth of fine-leaved aquatic macrophytes. Does not seem to require large open areas. Probably browses on zooplankton in the vegetation. Never seen in markets, but known from the aquarium trade (Ref. 12693). Uncommonly seen in aquarium trades but widely used as aquarium bait in Ho Chi Minh City, Vietnam (Ref. 57235).

生活在泥煤而且使洼地陷于泥沼。 (参考文献 57235) 出现于湿地,沼泽与池塘且大型水生植物密集生长的地方。 似乎不需要大的开放水域。 可能吃植物丛中的浮游动物。 从不在市场中见到, 但是已知来自水族贸易.(参考文献 12693) 稀有地在水族贸易中见到了但是广泛地在胡志明市,越南用作了水族馆诱饵.(参考文献 57235)
