There is very little to choose
between this species and Hypostomus
surinamensis
and in 2012 Weber et al. declared H. surinamensis
as a synonym of H. gymnorhynchus. This has
not been excepted in some quarters. Dark spots adorn
this species and get somewhat smaller in the head.The tips of the caudal fins extensions are
black.The Hypostomus genus
has 7 rays to the dorsal fin whereas the similar looking
Pterygoplichthys species have 10 dorsal fin
rays. Aquarium Care: As with most
of this genus, will do well in a larger aquarium,
although this is one of the smaller species in the
genera, and the aquarium well filtered. Water parameters
can be quite diverse for this genera. Diet:
Omnivore with a liking for green, tablet and frozen
foods.
