My clown barb is just kind of bouncing up and down in one place. Does anyone know what that could be from? I got him when I bought a few Arulius Barbs, he must have been in the school because I didn't ask for him. I've never seen one at a pet store before. He's cool and I'd like to keep him.

I know this could be from having no other clowns to school with but if it is something else I'd like to treat it. I have a video of it but I don't know how to post it.

Thanks in advance

Is he still doing it? and if so is it constant or off and on?

It's fine now. He was just bouncing up and down for days. I found another one in an arulius barb tank and bought. Now the two are happy as can be. I've never seen them for sale, just mislabeled. It's amazing the change. Now when I put my hand in to fix a plant or something those two are the first to nip at me.
