Unfortunately I lost my butterfly and the rest are soon to follow suit. I am trading my 90 for a 30 and considering reef. Way before an animal goes into the tank, I am going to make my self crazy with the facts. This time around I am going to take my time. I truly have a deep respect for the hobby and I took it for granted. Honestly, I feel it was placement of the tank. It is approx. 4 feet away from the sliding glass door. Hind site sure is 20/20. I don't know. I can't even get the LFS to take fishies to help them get better. (they do not have a qt set up yet) I wanted to thank all of you for your help. I will still be around, just not full of parasitic questions!!!
