Does anyone know why a Lyretail (christmas) Wrasse about 3-3.5 inches long in an established 75gallon, will seem to not be able to use it's rear fin, starting to sit on bottom, swimming in circles using only front fins, breathing seems more rapid. No visible signs of ich or any other skin related disease or parasite. The inhabitants are a yellow tang, goby, black velvet damsel, green chromis, pajama cardnal, clown and queen angel a hermit crab, an arrowhead crab, and three turbo snails. It is a live rock set up. Also have four aptasia's, although not for long. Water tests look good, slightly high PH, test showed a slightly purple color. The queen angel was added a few weeks ago and the snails addes two days ago to help clean the live rocks.I bought the snails after the Wrasse started showing these signs, seems to be slightly worse over past three to four days. The Wrasse has been with this tank for over a year as have all but the angel and snails. Thanks in advance for any help in this matter.
