make a mush.. go to the deli, get a raw jumbo shrimp, clams, scallops, muscles what ever they have.. total will under 5 bucks.. soak them all in r/o water including the flake (especially the flake) for 15 minutes, toss the shimp etc in a blender, chop finely... add some selcon and vita chem.. and waa laa.. much he will chomp that down
FYI frozen brine shrimp are about useless for nutrition unless they are "enriched".. you should thaw out all prepared frozen foods in ro water and rinse to remove phosphate
