I have a yellowbar angelfish, and my guide book says that he can be kept with "small polyp stony corals, as well as some of the more noxious soft corals." However, it doesn't say what these soft corals are. Does anyone have any idea? I just watched him destroy a beautiful colony of green star polyps before they could ever even extend. I have also had a rock covered with zooanthids picked clean overnight, and a small frag of xenia eaten over the course of a week, but I don't know if he had anything to do with these incidents. What soft corals can I keep with this pig of a fish?
