What would be the best thing to feed a silver barracuda? I hate to use guppies and goldfish for too long as they are nutritionally void. Would this fish eventually learn to eat silversides and shrimp from a feeding stick? I know the LFS has been stuffing him with goldfish the last month. Before you say my tank is too small I have already made arrangments with the local zoo/aquriam to take this from me when he gets too big
