JD's eating habits

[twisted01976]

Both of them used to eat flakes like there was no tomorrow. Now they seem to want nothing to do with them. I've tried another brand but no luck. They still eat the shrimp pellets and anything frozen I put in. I have never been able to get them to eat pellets other than the shrimp pellets, and I have tried 3 different brands and sizes. I have always fed them a varied diet so that is why I don't understand the flake thing. If anyone could give me some suggestions of higher protein foods to try, that would be very much appreciated. The shrimp pellets are high in protein but not as high as the flakes and I would really like to get them eating more protein again.
