Dorsal soft rays (total): 8-9; Anal soft rays: 1 -
3; Vertebrae: 28 - 29. Habitat: Found
in high gradient stream and rapids, over mostly boulder
substrate. Aquarium Care:Will
need a good water flow in the aquarium with a sand
substrate and plenty of hiding places. 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. 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. Sexual differences:
Males have better colour, a broader head and lips
and adult males possess longer ventral fins than the
females. Etymology: 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.
