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.
If you keep it in good water and with fine rounded substrate (sand or fine gravel), you'll be giving it the best chances of growing new barbels. It very much depends on whether they are recently lost or have been eroded continuously for a long time (in the latter case, it's unlikely that they will grow back again).
