Facultative air-breathing in the genus (Ref. 126274); The smallest among the Guianese Lasiancistrus since it hardly reaches 10 cm TL. Prefers the rapid zones where the depth is shallow, the substrate is rocky and the illumination is moderate. Found in association with Lasiancistrus brevispinis, Cteniloricaria fowleri, Ancistrus aff. temminckii and Genicichla ternetzi. Its small size, odd shape and bright coloration make this species especially interesting for aquarists (Ref. 35381).
最小的自从它之后在 Guianese Lasiancistrus 之中刚刚达到 10 公分 TL。 偏爱急流区在哪里深度很浅, 底部是岩石的,而且照明是中等的。 发现于邻近 短棘毛 鲶[Lasiancistrus brevispinis] , Cteniloricaria fowleri , Ancistrus aff。 temminckii 与 Genicichla ternetzi. 它的体型小, 奇数的形状与明亮的颜色使这种变成尤其受观赏水族爱好者喜爱。 (参考文献 35381)
