So I have a KoI Betta. He is totally normal except for the fact that he goes up to stuff and touches it and then shakes. It's hard to describe and I can't get a video because he doesn't do it when I have the camera open for some reason. So he will go to the corner of the tank, curl kind of into the corner (his side is basically touching both pieces of glass at the same time. Then he twitches and shoots away from it. I've seen him do this with the filter intake as well. Is there anything wrong with him or is it just weird Betta behavior? Other than that he is totally fine. If I ever get a video I'll post it.
