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).
最小的自從它之後在 Guianese Lasiancistrus 之中剛剛達到 10 公分 TL。 偏愛急流區在哪裡深度很淺, 底部是岩石的，而且照明是中等的。 發現於鄰近 短棘毛鯰〔Lasiancistrus brevispinis〕 ， Cteniloricaria fowleri ， Ancistrus aff。 temminckii 與 Genicichla ternetzi. 它的體型小, 奇數的形狀與明亮的顏色使這種變成尤其受觀賞水族愛好者喜愛。 (參考文獻 35381)
