Hi, I am not sure if this is a problem or not. I have a Bristlenose Plec which I bought two weeks ago. It has settled in well and is eating food and algae. It has suddenly started making sudden dives(it goes upwards but can't think of a better word) up to the surface and back down again. It only does it a couple of times a day. It is in a community tank with no aggressive fish and the water is fine.Any ideas welcome. Oh, and the tank has been running since last October.
