I put in a royal gramma in December. A short time after I got her, I saw a few spots and she was rubbing on the rocks. I feed well, use garlic, and keep my water prisitine. She seemed to clear up right away with no more problems. Then in January, I added an emporer angel. I didn't see any problems or spots until a few days ago - 6 weeks after the emporer was added. The gramma had several spots and was flashing constantly but the emporer wasn't symptomatic except for some discoloration and he appeared with what looked like the beginnings of HLLE. I was able to catch the emporer easily and get him into QT but thus far have not been able to catch the royal gramma and she is looking terrible. Today is the 5th day of QT coppersafe treatment and the emporer seems to be doing ok. He's eating like a pig, breathing normally, and I don't see any spots. He still looks a little discolored and there are 2 spots that still look like HLLE to me. I'm going to continue treating him for the full 30 days and I will allow the tank to go fallow for 6 weeks while he's in treatment. From now on, everything will be QT'd, fish will probably get a prophylactic round of medicated treatment for common diseases to try and prevent it from getting into the display.
