This species has no unique autapomorphies, the third (main) lateral bar uniformly wide (its width not uniform in other species); caudal blotch usually absent; no lateral spot or medial intensification of bars on side of body; absence of ocellus on dorsal fin; without abdominal blackening in mature females; palatine arms subequal; posteriad projection on ventroposterior angle of retroarticular
absent; articular with a right angle ventrally; an anteriorly directed pronounced convexity

Inhabits rivers and rivulets which have moderate to strong currents but is not found in the rapids. Prefers smaller rocks and gravel. Found up to 2000 feet of elevation. Omnivorous, feeding on algal filaments, aquatic insects, seeds and bottom detritus. Spawns in caves or crevices, preferring to adhere its eggs to an oblique or vertical surface. Produces about 200 offspring which feed on the parent's dermal mucus.
棲息於河，而且小河那裡有平穩或強烈的水流但是是不出現在急流。 偏愛較小的岩石與礫石。 發現向上到 2000 呎的海拔。 雜食性,吃海藻的絲狀突起，水生昆蟲，種子與底部碎屑。 產卵在洞穴或者裂隙,偏愛附著到一個斜或垂直的表面它的卵。 產生大約吃父母的表皮黏液的 200 子孫。
