The comb jellyfish is a midwater - deep sea jellyfish that is small, beautiful, and does not sting. I have seen them for sale. They're colors are incredible. People have kept them in jellyfish only aquariums. Because of their small size, and their lack of cnidocytes, could i add one to my tank? I doubt my fish will eat it or hurt it, as i have only peaceful fish and will only ever have peaceful fish. Could i add one to my tank? Sorry for the stupid question
