I can't believe I did this. I set up my QT and bought 2 clownfish, doing everything right. I was offered a free GSP and beautiful live rock about softball size and couldn't resist. The GSP and rock were from a mature 10-year old tank, which was in "perfect" condition. Unfortunately I placed both the Clownfish and GSP in my QT. All was well for one full week, fish very lively and eating well. GSP very happy. Today I notice a white speck on one of the Clownfish, dang! Fish are still very lively, swimming normal and eating well. I know, I know I should have never put the GSP/rock in the QT, but too late to look back now. So what do I do? Should I treat for ICK? WIth what? Will it kill the GSP? I'm less concerned about the GSP because it was free. I'm guessing that the GSP/rock probably has hitchhiker's - what should I do with it? Is there anything I can do to "treat" and save both (Clownfish and GSP)? Or should I just watch closely for the next couple of days, maybe I am jumping to conclusions too soon that it is Ick?
