Agamyxis is a genus of thorny catfishes.

Species

There are currently two recognized species in this genus:[1]

Agamyxis albomaculatus (W. K. H. Peters, 1877) (Spiny cat-fish)
Agamyxis pectinifrons (Cope, 1870) (Spotted Raphael catfish, Spotted doradid, Whitebarred catfish)

Distribution

This genus is found in tropical South America.
Description

Both species reach about 15 centimetres (6 in) SL.[1] These species both appear very similar; A. albomaculatus might be slimmer, have more spots and a different pattern on its caudal fin.[2]
Ecology

These catfish are able to make sounds by grinding their pectoral fin bones against their shoulder bones.[2] They can live for 17 years.[2]
In the aquarium

Both species in this genus are popular in the aquarium trade.[citation needed]
