Information:
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.

IUCN
Red List
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).
