|Size||103mm or 4.1" 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.
This particular species has spots only on the head. All fins are clear and each body armour plate is lined in black. The basic colouration is pale olive green. Aqualog shows this fish as L146/L146a and L187b. The real L146 (introduced in DATZ) is a rather unusually shaped but plainly coloured ancistrine loricariid also from Colombia. L187b is an Aqualog invention and only used here for reference/link back to the old Aqualog literature.
Variously and incorrectly labelled as C. thomsoni and others.
Some sources consider L444 the same as C. tachiraense. This may stem from a confusion about the Rio Tachira in the Rio Meta drainage, and the namesake river in the Maracaibo basin.
|Sexing||The males have however a somewhat 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 too fast in the current.|
|Distribution||Currently known from western piedmont tributaries of the upper río Meta and Guaviare basins, in departments of Meta and Casanare, Eastern Colombia, Orinoco drainage.

|pH||6.8 - 7.8|
|Temperature||20.0-25.0°C or 68-77°F (Show species within this range)|
|Other Parameters||Has more stringent demands on water quality than many plecos and requires highly oxygenated water when kept in warmer water. Medium hard water is also beneficial.|
|Feeding||Omnivore. Will eat algae and small live or frozen food. Some individuals can be weaned onto pellet food although this usually takes some effort and trial and error on the part of the aquarist.|
|Furniture||Worn smooth rounded or slightly flat fist sized rocks on a fine sand substrate.|
|Compatibility||A peaceful fish which can sometimes be a little territorial with its own species.|
|Breeding||See Shane's World Article|
