Relevant Information:

Habitat: The flooded margins covered by grasses are important microhabitats for H. francirochai, that is also very abundant in the lower stretch. A strong relationship with the submerged marginal vegetation was also observed for other species of the Hypoptopomatinae in Brazil (Costa 1987, Casatti & Castro 1998). Reproduction: Scatters eggs throughout the aquarium and are not cared for by the parents. Aquarium Care: Said to be a bit more problematic in the aquarium if good water quality is not adhered to. They rest on aquatic vegetation in the aquarium so long leaved plants are recommended. Cooler temperatures and a strong filtration with adequate current will fare better for this species and for this genera overall. Diet: Will feed on flake, algae, tablet foods and algae wafers. Etymology: The specific name francirochai: In honour of Brazilian psychiatrist Francisco Franco da Rocha (1864–1933), founder, Hospital Psiquiátrico do Juqueri (Região Metropolitana de São Paulo), on the occasion of his jubilee.
