I am just finishing up my first bag of fish food. I throw one scoop that is probably 2 cups of food and I now have catfish going crazy every evening when I feed. I only throw one time a day and the catfish have this gone within 2 minutes. Recently, I have seen bluegill hovering around and I will throw a few pellets and they nibble at it. But, when the catfish appear, I don't think any other fish can get into the the fray.

My first question is how do I know how much to feed? If the catfish clear this scoop within 2 minutes, should I feed more at one time, or feed more than twice a day?

Second, if I feed the catfish in the same area every night, would throwing some feed in a different location give the other fish a chance at feeding?
