I have a little veiltail in a 5gal all by himself, and he's active pretty much continually - always swimming around and poking around the tank. I have a HOB filter, and it apparently causes a reflection on the glass, because every time he passes it he flares and puffs up at the glass for a few seconds..then forgets about it, swims off, and repeats two to ten minutes later. All day.
He's eating, sleeping, generally being happy and healthy...should I do anything about this? Will it wear him out, or is he fine?
