I know where I got the parasite, it is ick. I got a naso tang a couple weeks ago. I quarantined him for 7 days in copper. He was doing great and when I put him in the main tank he was ok for 1 or 2 days and started to get ick. Unfortunately I work 24 hr shifts and by the time I got home to get him out and quarantine again he was covered along with some fish that has been in the tank for quite awhile were starting to get it also. Since I have lost about 8 fish. I've even pulled the sick fish out and quarantined along with antibiotics for a secondary infection but still lost them. As of current all the fish left look pretty good. I put the uv in to take care of bacteria and some parasites free floating. I hope I am done with it. I've been feeding with garlic and metrodinazol. The fish I have left are an Anthia, occelaris, damsels, chromis, eight line wrasse, and a tomatoe clown. My water parameters are near to perfect. Salinity 0.25, ammonia 0, nitrite 0, nitrates 2, ph 8.2, calcium 450. Thats all the test I have. Did a 20 gallon water change last Thursday.
Thanks
