Parasite on Naso?

[robchuck]

I acclimated a Naso Tang to my tank yesterday morning. It appeared healthy (no visible diseases, no torn fins, no signs of stress, no heavy breathing; it is even eating already) as I went to bed last night. This morning I woke up and noticed a BB sized dark-green/dark-brown growth on the fish's body near the base of the dorsal fin (I have attached a photo to help ID; it's not very good quality, but it was the best shot of the subject I could get). It almost looks like a pod jumped on the Naso's back during the night. Is this possible/common? If so, what methods should I take to help my Naso? The system is a 150 gallon FOWLR. I have a pair of cleaner shrimp in the tank, that have tried working on it but gave up and jumped off pretty quickly. My water readings are as follows: Ammonia-0ppm, Nitrite-0ppm, Nitrate-approx. 10ppm, pH-8.2, SG-1.023. I appreciate in advance any and all advice.

Can't really see anything from that pic. Is it a wound looking problem or does it look like a parasite is attached?
Not unusual for a single parasites to come out of hiding when a fish is added to the tank. I'd keep an eye on it to see what develops; perhaps the cleaners will get a chance to work on it. If not, you will have to remove the fish from the main tank to treat it.

Thanks for the response Beth. Upon observation today, it definately looks parasitic. It almost looks like a rolly-polly. Unfortunately, that's the best picture I have been able to get; I hoped it would be enough to back up my description. This fish is behaving as I would expect a newly added Naso to behave (timid, but is out to explore, and graze on the veggie clip). I will take your advice and let the cleaners give it a chance. If by chance it remains after a few days, what method would anyone suggest for removing the parasite?

Does it resemble this creature?? For your sake I really hope not.
