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
