Betta Fish: My Betta Stu

I’ve never owned a Betta before him and I always wanted to and he is such a difference from my other fish, anytime he sees me he comes swimming to the front of the tank and it’s so cute. He’s named after the scream movie because he is violet and a shrimp haterand ate one bc he’s fat lol. Only thing I can’t do is get him to flair, tried showing him himself, trying showing him a prettier Betta on my phone, tried insulting him but he doesn’t care
