this is probably oversimplifying this but if a harlequin shrimp is going to eat what it eats in the wild, why is it unethical to have one in a tank eating the same thing it would be eating if it was in it's natural enviroment? i would understand if there was a breeding program where the numbers of these shrimp are artificially inflated and more natural food had to be taken from the ocean but a shrimp has to eat so it might as well be where i can see it.
