There are over 40 species of Chaetostoma and classification is not easy. Most species offered for sale will grow to 10cm, although a few species can reach nearer 20cm, which should be considered in case a larger species is purchased unintentionally. The fish pictured is likely to be 'L146' or C. thomasi. The fish come from clear, well oxygenated high altitude streams. In the aquarium this means they prefer slightly cooler water and strong filtration and aeration.
These are peaceful fish, although some may show occasional territorial behaviour towards others of the same family.
Provide hiding spots in caves or under rocks or wood and feed on sinking foods including vegetable matter and a small amount of meatier foods.
