I feed algae waffers, floating cichlid 1mm pellets, and flake. For 3 different types, sizes of fish.
My wife actually feeds them, I see the residue in the morning when I get home. I want her to be involved and she can get irritated when I tell how to do it.
The smaller fish can't handle the 1mm pellets until they soften up.
My two biggest eaters have been holding eggs every month for a week or so. So then the extra food really piles up.
My native creek chubs, clean up crew, love cat food, but won't touch premium Hikari gold. They get most of the tank alge, and the flake that was intended for the 1" juveniles.
The chubs keep the tank dictator busy so the other fish will come out.
The algae wafers are only eaten by the mbuna, they are not eaten until they soften up after a few hours.
Some day they will all be big enough to not feed flake. This would help also
