My betta, Doyle, is a biter. Every time I have my hand close to the top of his tank (when I'm feeding him, fixing his filter, etc) he lunges at me and tries to bite me! I was wondering if this is normal behavior for a betta or if hes hungry or something. lol. I feed him 3 pellets every other day and 2 pellets and a blood worm the other days and I let him fast on Saturdays.
Oh, and I have a cave in his tank and he never goes inside of it. :( Is there I way I can make him go in there or is he just not a cave kind of betta?
