Hello. I posted in betta care but realize now that i should post here. My betta has dug a bit of a trench beside his vase and recently rubbed the scales off the top of his back. He flicks and glances off of decor, or he did, but he doesn't anymore. He stopped eating yesterday morning too. I've never had a betta before him and he was always a little off behaviourally so until I noticed the missing scales I didn't think anything of the strange things he was doing. I'm going to a fish store tomorrow morning to get meds, but I don't know what I need. Help anyone?
