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. 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
Chaetostoma palmeri has a very restricted
range (extent of occurrence (EOO) is estimated as
2,400 km²) and occurs at one location. It has
a high sensitivity to changes in water quality, this
means that threats from a number of different sources
influence the extinction risk of the species including;
pollution and erosion related to mining activities
and run-off from cattle ranching. Together these threats
are leading to a continuing decline in habitat quality,
resulting in this species being categorised as Endangered
