I have all of my fish on a home made diet. It's squid, octopus, cuttlefish, scallop, mussel, and seaweed. I puree it lightly in a blender with a vitamin supplement and froze it in an ice cube tray. I then use a razor to slice bits off (I do several at a time and put them in a tupperware container back in the freezer) and just thaw it out in a cup of aquarium water when I'm ready to feed them. They love it.
