paradise fish eating habits

Question
hi again-thanx for the advice about the algae on the plants; now, our fish has become finicky about what he eats. flakes used to suffice be now he only wants bloodworms. is this weird?

Answer
Dean,

No it is not weird. Fish, just like anything else, know what they like better than other things. Continue to feed only the flakes until he is eating them again. Make sure the blood worms are a treat and only fed once a week unless they are frozen blood worms. The freeze dried blood worms to fish is like us eating deep fried chicken. We love it but its not good for us to eat all the time. The frozen foods are better and can be fed more often. Once he realizes that the blood worms are a treat and not the everyday food, he will start eating again.
