I have noticed some weird behavior in my albino catfish. I have 4 of them and they go crazy in the evening - swimming back and forth along the front of the tank. Usually it's 3 of them doing this and most of the time they crash into each other head on! They even crash into other fish that are swimming by. Can they see? I'm starting to wonder if they can't see since they crash into each other. Has anyone else seen this behavior?
