considering i see fish using tiny underwater grills to cook there food all the time in the wild, so best cook it up at home
ok ok, ill stop. raw is much better for your fish, as cooking kills off the nutrients you want your fish to get. most people get shelled/de-veined shrimp, but i try to get whole shrimp when i can for my larger fish. when they eat in the wild, noone shells or veins their food. plus, theres got to be other vitamins and stuff contained in their shell and veins that they would otherwise miss.
