Betta acting agressive

[Yoemen]

I have a betta and 3 corys in a tank together. Water parameters are all in good shape. Made the mistake of putting in some plastic plants so my betta tore his fins, yanked them out and replaced with silk plants, and have been medicating with melafix. Doing %40 water changes weekly, but have noticed recently that the beta has been chasing and hounding my corys. I feed him 4-6 blood worms 5 days a week and feed the corys 1 shrimp pellet so I don't think it is a hunger thing.....

Any ideas or is he just psycho

He's a betta fish. Some of them do that. I doubt he'll hurt the cories and there are enough in there that he'll take turns bugging them. He won't fixate on a particular one. He may just stop doing it at some point.
