Hi folks. First post here from Northern Ontario.tank is about 2 months old. Well cycled.have 3 fish and lots of cleaners. Brown algae beginning to show. Was recommended to get a sandsifting starfish (sss). Had him about 6 days. Hardly ever seen. But today its motoring around the 100 gal dt and now climbing the glass.reaches the surface then hangs one leg out on the surface as if filtering. Looks healthy but from reading up I suspect its hungry. Have tried to give it chopped raw shrimp but won't take it and walks over the food pellets on the floor.. considering going to supermarket to get claims. Any thoughts on this behavior.
