Cleaner shrimp perfer more space you could put one in if you really want to not the best choice and Coral banded shrimp just need a lo of spase just check this site under inverts
So I guess it's a good thing that I'm planning to move my BBS to the 29 soon and was going to put either a peppermint or cleaner in the 10g. In your experience, are the peppermints as "friendly" as the cleaners?
