I make my own fish food, and I rotate each of them. Use all Raw/Fresh ingredients and throw it in a blender then put it in ziploc bags and freeze them. Break off a chunk that will last 2-3 days, melt in a small container (refrigerate after feeding). Big money saver too to make your own - $15 worth of ingredients will last you easy 6+ months if you have a local Asian Farmer's Market.
batch 1 - oysters, clams, seaweed (nori), smelt, shrimp
batch 2 - octopus, squid, brine shrimp, seaweed (nori)
Next round of batches, I will add Spirunila Powder to it. I read good things about this.
This is not an exact science, but each day I would start with flake/pellet first thing (because once your fish eats fresh they seem to turn away flake unless its first thing when they're hungry), then the 2nd & 3rd feeding I would give them some of the pre-made batches (thawed out of course).
My only issue with this would be the mecury content building up in a closed system.
I believe in variety.
My live stock include: pair of clowns, pair of firefish, yellow tail damsel, yellow tang, neon dottyback, and a fire shrimp. All healthy and happy.
