Because I have a weakness for small things, I ended up buying four 1/2 inch Sexy Shrimps. Ecxept for some snails they are the only mobile occupants of my 21 gallon cube tank. I am wondering if any fish would be safe to add the the tank. If so, which ones. I already have a Yellow Clown Goby, and two Ocellaris clowns in the other tank.
