This undescribed species of
Hypoptopoma is found amongst Brazilian imports
and is recognisable by its red ring around the eyes.
Habitat: The species of Hypoptopoma
typically occur in streams of slow to moderate current
and muddy to sandy bottom with marginal emergent vegetation.
Sexual Differences: Male urogenital papilla
short and conical, covered by anterior flaplike anus.
Males with patch of tightly arranged small odontodes,
variably covering first to fourth plates of ventral
series, lateral to urogenital papilla. Males with
poorly developed soft-tissue flap along posterior
margin of pelvic spine. Female anus tubular, without
separate urogenital papilla. In females, size and
arrangement of odontodes on plates lateral to anus
similar to adjacent plates, without distinct patch
of differentially arranged odontodes. Female pelvic
spine without flap of soft tissue on posterior surface.
Aquarium Care: Will not bother other
fish in the aquarium. They like to hang on to thin
stalks of plants so they can see around it with their
laterally located eyes. Provide shaded hiding areas
in the tank with rocks or cave-like structures. Diet:
Feed an all round diet but prefers a vegetable diet
such as algae, spirulina tablets and cucumber/courgette.
