Habitat: It is a predominantly nocturnal species, during the day it hides in caves or under fallen sticks. It inhabits heterogeneous backgrounds; sand, pebble, rock and mud; fast and moderate flow waters not very deep (0.3-0.9 m.) and abrupt and excavated margins with riparian and riverine vegetation Presence of abundant periphyton and allochthonous material. Sexual Differences: Males have better colour, a broader head and lips and adult males possess longer ventral fins than the females. 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. Etymology: The genus name Chaetostoma: chaeto-, bristle; stoma, mouth, referring to the bristles on cheeks of males. The specific name fischeri: in honour of Steindachner’s “dear friend” (translation) W. Fischer, who provided a collection of river fishes from Panama, including type of this species. Remarks: Chaetostoma fischeri is currently thought to have a broad that ranges from eastern Panama southward to northwestern Colombia. Extent of Occurrence (EOO) is estimated to be 97,783 km2. Total population size and population trend have not been quantified, but limited ichthyological surveys suggest that this species is uncommon throughout much of its range. A number of localised and regional threats exist, including land-use change and deforestation associated with agricultural expansion, widespread artisanal and commercial mining operations, and pollution from industrial and domestic waste water discharge. While existing threats are likely to be producing localised negative impacts on habitat availability and quality, there is currently no indication of major range-wide population declines. Therefore, C. fischeri is assessed as Least Concern. Continuing taxonomic work on the species will likely lead to further shrinking of the range of the species and subsequent reassessment will be required (IUCN 2020).
