OK. I rescued this Betta from Walmart about a week or so ago. Hes really pretty and not very aggressive. But.... He won't eat anything except freeze dried blood worms. I swear.... I put a couple flakes in the tank, he sniffs them, then gives me this 'You have GOT to be kidding me' look, then off he swims. Drop a couple blood worms in the tank, and ohhh yummy yummy. Whats the deal?? Is this normal Betta behavior?? And I would imagine that a diet of strictly worms isn't good for him. Any ideas or suggestions.
