I got a beautiful betta just two days ago. He was in a tiny cup that you use to drink coffee out of, and the water was so cloudy. I put him in my 10 gallon tank, and even though he was in such harsh conditions, he's doing great. He's got quite the personality, he swims everywhere, he's very active and he likes to go in and out of the plants. I have one problem though, he won't eat. I've tried feeding him tropical fish flakes and betta pellets. All he does is look at it, put it in his mouth, and then spit it out. I can tell he's hungry, but whenever I give him food he won't eat it. Help?
