Nasos are so hardy and ready to romp. You have a skimmer running and good oxygenation I take it ? Feeding the fish nori, spirulina flake, mysis?

I feed nori, mysid,brine,krill, spirulina, formula 1, new life spectrum, ocean plankton, blood worms...And i think thats about all that i can think off

Sorry to hear buddy.

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.

We do already have a QT tank, although when a fish of that size, ~9" comes around a 20g QT isn't sufficient, or humane.

I have never once heard to avoid large Naso tangs, and I myself did work in the industry for a short amount of time. Where did you hear this? How common is this knowledge, has anyone else heard of this?

I would tend to agree with that in general if the fish is coming from the wild (as opposed to someones trade in). My sense is that adult fish may have their feeding habits set and find it harder to adapt to unrecognizable forms of prepared foods.
Any other thoughts?

It is probably the reason together with the stress of the travel here.

The key with the large adult tangs and angels as well is to SEE them eating at the LFS. (A good practice for buying all fish. Don't believe the LFS if they say they had just fed the fish). Sadly most large adulst tangs and angels wont eat.

Catherine. It is from my own early experience with Naso and other large fish like angels. I have also read it but can't find the cite immediately.
Was the naso eating when you bought it?

Thanks
