My dad's 55 gal. saltwater tank is basically a small chunk of the sea in a glass tank. It has tubeworms, TONS of bristleworms, limpets, some amphipods about a centimeter and a half long(!), and above all, literally TONS of small, somewhat microscopic isopods, amphipods, copepods, snails, barnacles, worms, etc. My dad wants to get rid of some of them so would a scooter blenny survive in a tank like this and feed off the isopods, amphipods, etc?
