I typically feed my fish twice a day, and have been trying a variety of frozen foods (including "home blends") on them. Live foods are harder to get, but I do feed them roe a few times a week. Nothing I've, tried, however, gets a better feeding response than flakes. I'm sure it's the equivalent of junk food, so I try not to feed them it more than three or four times per week. How many of you rely upon flakes extensively?
