I feed my haps and cats 3 small meals daily:
Meal one and two-
6 Large Hikari Cichlid Bio-Gold+ pellets (large floating)
10 hikari cichlid gold pellets (small floating)
15 hikari Cichlid excel pellets (small flaoting)
2 small Hikari bottom feeder (fish meal, krill based) wafers
1 large spirulina wafer
Meal three-
2 frozen brine shrimp cubes.
2 sprirulina wafers.
15 Hikari excel pellets
The way i see it, all 3 meals have both protein and fiber, its a healthy , balanced diet imo and i am a human personal trainer and nutritionist.
The water perams are always stable and there is never any left over food floating around, the fish are also looking lean and healthy so i think this diet is working pretty well for them. I feed them meal one before work in the morning, meal two when i come home at half past 4 and meal 3 before bed witch is usualy at 10 or half past 11 at night.
The key to a good diet is variety and having small meals throughout the day. just my 2c. Cheers-
Darren
