i keep some bettas around cuz they're pretty, and i was wondering if they can have seizures. i got him a couple weeks ago at petsmart just for the hell of it really, and today he just started swimming in circles. big ones at first, but near the end they were really tight, nose to tail, so fast i thought he was going to spin right out of his bowl! and then he lay at the bottom of his bowl gasping, and nearly bent double, until he died. really unusual. the petsmart lady said stress, but she said betta-fix would cure him too, so i don't believe her. so... if they can't have seizures, what happened to my betta?
