Not less than 148 species are counted to the genus Hypostomus, but no five of them appear more often in the trade. Special is of course H. luteus with its sail-like dorsal fin and the bright yellow coloration, but most species are “plecos”, brown or gray with black spots. In addition, most species grow quite large (20-40 cm) for normal aquariums.
An exception is Hypostomus roseopunctatus. It comes, like also H. luteus, from the south of Brazil, as well as from Paraguay and further areas of the inflows of the rivers La Plata and Rio Uruguay. Whether the species is really identical with L311, which was exported from the Brazilian state of Bahia, which is much further north, is not clear, but in the trade one hardly cares. Clear recognition mark of the only extremely rarely imported species is the small number of teeth per maxillary branch, as our animals show. The pink stippling is also very characteristic.
Hypostomus roseopunctatus becomes about 25 cm long, therefore our specimens are almost fully grown. The two fish shown in the photo are probably a pair due to the physical differences. These catfishes are very tolerant among each other and towards other fishes anyway.
For our customers: the fish have code 26480-L 311-7 on our stocklist. Please note that we only supply wholesale.
