So I live in a little po-dunk town and the only silversides I can find is what the fish stores have and want to charge and arm and a leg for. Is there something else I can use in place of the silversides I can get at the fish market? I was wondering about salmon, I can get that for the same price as silversides for twice the weight. I know my rays love it, but is it enough in proteins and fats like the silversides? Can I feed it to my Anemone?
