Etymology Greek, chaite = hair + Greek, stoma = mouth  
Jump to next section Species Information
Identification The genus Chaetostoma is not straight-forward 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.
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.
Jump to next section Husbandry Information
Furniture Well rounded stones stacked to replicate a river bottom and provide caves.
Breeding Spawns in shallow, fast flowing water on the underneath of a flat object. Male, upside down, guards an adhesive clutch of eggs by, more or less, covering it with his body.
