Dorsal soft rays (total):
8-9; Anal soft rays: 1 - 3; Vertebrae: 28 - 29. Found
in high gradient stream and rapids, over mostly boulder
substrate. The specific epithet spondylus
is in reference to the tuft of odontodes on the trunk
lateral dermal plates that resemble the thorny projections
of the bivalve mollusk known as spiny oyster. Aquarium
Care:Will need a good water flow
in the aquarium with a sand substrate and plenty of
hiding places. Diet: Great algae
eater, but you will have to subsidise this food with
algae wafers and vegetable foods such as cucumber,
zucchini and lettuce. Will also except tablet and
worm foods. Remarks: The Chaetostoma
species are not the easiest to maintain as the mountain
stream species will need a water current to provide
oxygen-rich water. The species that are exported usually
originate from warmer waters so are a bit easier to
keep than the mountain stream variety. Sexual
differences: Males have better colour, a
broader head and lips and adult males possess longer
ventral fins than the females.
