Thank you all. I removed the one and am on the look out for more. I will be ordering some coral rx and start dipping. I was thinking of trying the method with bayer bug killer. Whats strange is my zoas never closed up. since this is my first tank ive made some mistakes like not QT'ing any corals. But that will change when we get to out new house as I just bought a 93 marineland cube RR. I must admit I would have never found this little guy if my 3 yr old wasn't playing around and completely made a mess of the tank. so I guess someone owes someone an apology.
