I also feed Cyclops and rotifers cubes as well as a homemade frozen food made from 1 lb of shrimp, a bag of seafood medley from the grocery store( contains squid, octopus, mussels, shrimp, and clams, but low or no salt), I'll add in a sleeve of formula 1 or 2, emerald entrée, maybe some krill or silversides, some garlic and then I run it through the food processor until it's a paste. Then I put it in a gallon freezer bag, smooth it out, let it freeze, then cut it into small cubes to feed with. It costs me about $30 for almost 4 or 5 months of food, depending on how big I make the cubes.
