I had an outbreak of Ich that took out several fish. The last fish that died was about a week ago and I have a yellow and blue tang and 6 line wrasse that seem to be fine. I did a 2 week treatment with kick Ich and turned the tank temp up to 82 degrees. I am looking to add percula clowns, a dwarf angel, dotty back, and watchman goby. what is the best way to start to add new fish after an outbreak?
