One of my L-260's hase been acting really strange lately. After apparently being cured of a disease decribed here:
http://www.forum.planetcatfish.com/viewtopic.php?t=993
it now seems to have problems swimming properly. Sometimes i see him lying on his back, and a few minutes back, he did a loop when trying to move...

What is wrong with him?

Nobody knows what's wrong? I am really worried about him, his belly (mostly the front part) and suckermouth is redish and I'm not sure if he is able to use his suckermout normally...

Help!

I'm starting to think he may have a damaged swimming bladder, when he tries swimming, he seems to be sliding accros the gravel instead of flotaing just above it as he used to...
