I have had my tank for 4 weeks. It has completely cycled. Two weeks ago I added a cleaning crew. Everything has been perfect. I bought my first fish last night, 2 True Percs and one XS Blue Tang (Dori). Woke up this morning and one of the Percs had perished. The other one is fine but the Tang is acting weird as well. Checked all my levels and everything is great. My LFS just got the percs and tangs in on Tueday. Maybe it's that. I don't understand and I am a bit depressed. Any opinions about what could cause this? Thanks,
