Colts can react like that to moving to a new tank and may need some time to adjust. They are not as moody as some of the other
soft corals like toadstools, but may go into a funk for a while then snap out of it. Further complicating the whole matter is the loose way common names are tossed about. Colt is generally meant for the Cladelia genus, but in the trade any of several similar looking corals can be labeled as whatever strikes someones fancy. Good luck with your new coral
