Just setup my new 120 g tank, now will be moving almost everything over from my 75g. Wonder with a fresh start what kind of CUC I could use, was thinking 2 fire shrimp and 2 cleaner maybe some bristle star fish as I don't really want crabs anymore. Or anything big like turbo snail as I had them wreck alot stuff . Would what I'm thinking be a good CUC or should I get something else. Also I don't like empty shells in my sand bed.
