Size 76mm or 3" SL. Find near, nearer or same sized spp.
Identification The genus Chaetostoma is not straightforward to identify, but as a general rule, the species has spines behind the gill-cover (interopercular odontodes), no plates on the abdomen, and aside from C. platyrhynchus also lack plates on the snout edge. Different from Ancistrus by not having fleshy tentacles on the snout.

C. changae can be separated from its congeners by the conspicuously banded dorsal fin; presence of fleshy excrescence on posterior tip of supraoccipital; typically 9 branched dorsal-fin rays (rarely 8 or 10); and evertible cheek plates with 2-4 hypertrophied odontodes.
Sexing The males have however a larger and broader head, slimmer ventral sides and disproportionately large pelvic fins. Perhaps the over-sized pelvic fins play a large role in the fertilization of the eggs. By inverting these over the clutch of eggs, they prevent the sperm cells being carried away by fast water current.
General Remarks Originally issued L147. This number was later reissued to a Venezuelan loricariid from the Orinoco.
