Just made some 2 weeks ago, and made WAAAAY to much. Like 4 gallons of it!
Basically just went to the asian market and got random fish fillets, scallops, octopus, shrimp and so on as cheap as possible. got about 10 lbs total, along with some fish eggs and a big pack of nori, then got a bunch of frozen brine, mysis, bloodworms, large mysis, krill, cyclopeeze and random coral foods.
Blend up the fish and stuff to a decent size, then take about 1/5 of it and blend the hell out of it(fine coral food) defrost the frozen stuff, mix it all and put 6 cups in a gallon zip lock and refreeze.
Stuff is magical, if a fish doesnt eat in my tank there is simple no hope.
