It is a 29 reef tank. The only fish will be a pair of percula clowns and a pair of green clown gobies. I already have a couple small yellow zoanthids, a small colony of star polyps, and (if it settles in properly) a leather coral. They all came in on live rock. I want some shrimp. I like the cleaner shrimp, I think they would be a good addition. I also really like the peppermint shrimp. How many could I have in there. Two of each? One of each?
