Etymology	Greek, chaite = hair + Greek, stoma = mouth.
Species Information
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.
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	Before assignation to an L-number in November 2010, this species was known as Chaetostoma sp. `Villavicencio II`.

IUCN Red List Category	Not Evaluated
pH	7.0 - 8.9
Temperature	21.0-29.0°C or 69.8-84.2°F (Show species within this range)
Other Parameters	Occurs in streams and rivers with channels 8–50 m wide, shallow depth (0.30–1.3 m), moderate water speed (0.34–0.62 m/s), well-oxygenated water (6.1– 9.5 mg/L), warm temperatures (21–29 °C), slightly basic pH (7.1–8.9), and high conductivity (20.4–269.0 µS).
Husbandry Information
Furniture	Well rounded stones stacked to replicate a river bottom and provide caves.
Compatibility	In tributaries to the upper Guaviare River, C. chimu has been observed in sympatry the congeners C. dorsale, C. formosae, C. platyrhynchus and C. joropo.
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.
