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.
This one I think is a Corydoras maculifer.
I think the one on the left is Corydoras paleatus, but uncertain. The one on the right maybe Corydoras melanotaenia
right, the first two ones are C. sodalis and as for the C. paleatus? the picture is not good enough.
The right one in the picture is might be C. melanotaenia (something slightly irritates me, but I cannot tell what), are the fins yellow ?
