Hi, I am Tarun from India. 4 days back I put a lunar wrasse, a queen coris wrasse and an emperor angel in a qt tank. I took those 4 days to slowly ramp up my coppersafe dose to 1.64 ppm (checked with a hanna HR checker). Though the emperor was eating at the lfs, yet in my qt I did not see him eating. Today morning I found the emperor dead but the other 2 wrasses are fine. Is it something wrong that I'm doing here? Earlier I had a cherub angel who too died post dosing coppersafe. Should I switch to cupramine in the future with angels only and treat others with coppersafe? Are angels not compatible with coppersafe? My qt has strong aeration and is at 27ppt salinity.
