We have a Bristle Nosed Catfish who is acting a little strangely - we spotted him just now not actually sucking onto anything. Is this normal? Is he ok or is this like we assume and a sign that he's on his way out? I really hope not, I'm quite attached to him!! All that we have in the tank with him are 3 neons and about 8 small guppies and all the others seem fine.
Any suggestions greatly received

Cheers
