We have a 150 gallon aged reef tank with plenty of copepods, currently we have a mystery, filimented flasher wrasse along with the two dragon face pipefish and have had no problems with compatibility, wanting to add three leopard wrasse are they particularly aggressive towards pipefish or do you think they would be O.K. ? Just wanted to say we have orderd almost all of our fish and corals from you and are always impressed with the quality of your livestock.
