Leiarius marmoratus

10. February 2021

There are two species of catfish in South America that look like siblings: Leiarus marmoratus (called “Achara” by the natives) and Leiarius (formerly: Perrunichthys) perruno. Both species attain a length of about 60 cm, have the very same leopard pattern and the long, ringed whiskers. But there does exist an easily recognizable difference: Leiarius marmoratus has 10-11 rays in the dorsal fin, L. perruno only 8. The fish usually have the dorsal fin erected. So it is pretty easy to count the finrays on a sharp photo.

Due to the attractive pattern and the peaceful nature of the fish (any tankmate that does not fit as food will be ignored), acharas are much sought for by enthusiasts that love big fish. However, they are only rarely available on the ornamental fish market. Currently we have a number of very charming youngsters from Peru in stock, which are 5-7 cm long.

For our customers: the fish have code 265202 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in limited numbers only!
