生物学特性     字汇 (例如 epibenthic)

Prefers rocks or marginal vegetation of flowing riverine channels to lagoons or backwaters (Ref. 7248, 52193). It feeds on a variety of food including detritus, algae and plant material, insects, snails and small fish, and scavenges readily (Ref. 7248, 52193). Eggs and larvae of cichlids have been reported in stomach of this species (Ref. 78218). Oviparous (Ref. 205). Breeds during the summer rainy season (Ref. 7248, 52193), with a peak coinciding with heavy rains in January to March (Ref. 13337). Juveniles move off the floodplains when water recedes (Ref. 13337). Grows to a large size (Ref. 246).

偏爱流动到舄湖或洄水区的河峡道的岩石或杂草丛。 吃多种食物包括碎屑,藻类与植物,昆虫, 蜗牛与小鱼, 而且轻易地清理。 卵生的.(参考文献 205) 在夏天期间进行繁殖雨季。 (参考文献 7248)
