Stress

[naesco]

Sorry about your tang.
I have a couple of suggestions for you to ensure you are sucessful the next time.
1. Avoid large naso tangs. Even if it survived it is likely that it would refuse to eat. Choose one around 3 inches. All LFS know this. Why did they sell it to you?
2. Set up a simple quarantine tank now. It is a small investment and will avoid a repeat. In the very likely event that the new tang has ich you can treat it in the quarantine tank. You can keep the lights off to reduce stress in its new home.
