I have a 55 gallon reef tank with a male lyretail anthias, orchid dottyback, and yellowtail blue damsel. I had a yelllow watchman goby in the tank but he did not like the anthias......thus he hid all the time and did not eat. I removed him from the tank last night and was wondering what other fish would do well in this mix. I have been told that blennies, other gobies and fairy wrasses are not good choices. Anyone have any suggestions? Thanks..........
