Was Tetracrisps. I tried dry blood worms which he didnt take also. Soaked some in garlic water(we had no real garlic so i put the pre chopped garlic in boiled water, mixed and let cool) which he ate. My BBS didn't hatch for me which i planned to try feed him. I went out and bought some Bettamin, which he refused to eat. So i'm now starting to show him a mirror as i read about the confidence boost earnt by scaring another betta out of their territory. And i also gave him a little "friend" to chase. Just a guppy. He eats now that he sees the guppy eat
