Yeah, should be, this'd be my ideal regime, or is when i can get to the LFS...
I feed all flake 4 days a week, (although i use two different flake foods) maybe with a little freeze dried daphinia....
Live foods 2 days a week, mainly daphnia, a little brine shrimp, but blood worm only occasionaly
1 fast day a week, unless there is a reason such as stress or illness to be extra careful with them, on fast day i feed a little bit of pea and thats all...
I've had no health or constipation problems, sorry my fish have no health or constipation problems
you'll find your own feeding regime but bare in mind that its easy to overfeed and an all flake diet might eventually be bad for your fish....
Lots of variety basically....
