Description: Vertebrae: 28 - 27. This species is distinguished from its congeners by the presence of an elongated dark spot along the middle caudal-fin branched rays, not involving the lanceolate plates at the base of the fin; the spot is typically extended over equal number of upper- and lower-lobe branched rays and along more than two thirds of the ray length. 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.
