1.) I will be soon purchasing my 55gal tank for keeping an s.bandensis, or two. Now my dream would be to have this tank as a soft coral tank too. ie. Would it be possible to keep a cuttle in a tank with zoo's, shrooms etc... 2.) Coming from reefing I am used to having a clean up crew in the tank. As shrimp and other such invertabrates are a staple foodsource for cuttles, what kind of clean up crew will be safe for me to have? Thanks in advance.
