Did you know fantastic help is an anagram of Planet Catfish? This forum is for those of you with pictures of your catfish who are looking for help identifying them. There are many here to help and a firm ID is the first step towards keeping your catfish in the best conditions.
It's not often that I disagree with Silurus, but I don't think the fish show in the photos is a Schizolecis , the dermal scutes aren't keeled strongly enough. I would expect it to be a Hisonotus spp. (formerly Microlepidogaster) frequently imported from Paraguay as "Otocinclus sp. Niger"
They are neat little Loricariids, they do quite well in planted aquariums and breed quite readily in a similar fashion to Corydoras. They scatter their eggs around the tank in various locations (plants, glass, wherever).
IMO Schizolecis is clearly different than that shown and is a MUCH rarer import.
