Relevant Information:

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. 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.

IUCN Red List

Chaetostoma palmeri has a very restricted range (extent of occurrence (EOO) is estimated as 2,400 km²) and occurs at one location. Iti 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 (needs updating IUCN 2016).
