Still not 100% sure. Was great for a week then on the 7th night stopped eating and started breathing heavy,flashing,rock scraping, erratic swimming... I put CP in the tank and by Saturday morning the scribbled and juv FP were dead, the male was still hanging on so I think it was velvet? Not sure how it happen, 125g QT that was up and running for 6 weeks with nothing in it. They came from Brian at Reefwise and he doesn't run copper and had the scribbled and male for over 2 months before I received them. So I'm lost to say the least. I will be Formalin dipping every new arrival and starting TTM or CP right away. No more waiting for a fish to not be stressed from shipping and eating with gusto since it just blew up in my face
