Mysterious marks on my Naso Blonde

[BruceLeroy]

Every Naso Tang I have seen has little scratches or marks on its body. I have been told it is from rubbing up against the rock durings it aclimation when they are shy, but mine looks like it has huge white markings all over (even next to his mouth.) Mine has been in the tank for 3 weeks now, and he is very comfortable and friendly. He comes out when I walk up to the tank. His diet is great and he heats everytime I put his food in the tank. Am I worrying to much about nothing, or could this be more then scratches from the LR?

I also noticed a little ich on his pectoral fins today. This is what made me do a double take on my suspisions.

I have referenced this website and I haven't seen what my Naso has, so the comforts me a little.

I think you stated your problem.

I don't think the rest of the marks are from ich. I have been noticing the marks increase over the past week. I only mentioned the ich, bc that was when my concern raised. The ich is very minor right now (like 5 dots on his fins). I only mentioned that beause it is a sign that he is stressed, and could be caused if these marks are something else attacking his body. They could be little scratches from the rocks at night I suppose, but he seems extremely comfortable in the tank during the day. Experienced hobbyist here have told me not to worry too much if his diet is still strong. I just wanted to get a second opinion. I would hate to think the guy is suffering any.

Also, this is my first coral tank with fish. Previously I have had FOWLR and could treat the whole tank for ich with medicine. I have been told those medicines are bad for the coral. What do I do now? I dose his lettuce and seaweed in garlic. Temperature stays pretty consistant. Is there anything else I can do?

If it has a little Ich visibile now, it will have more next month, and more the month after that.
You really should treat all the fish for Ich now before they are all infected, Treat all the fish outside the tank (QT tank) using Hyposalinity

If it has ich then most likely it is scratching itself against the live rock in order to relieve itself. Is this the only animal in the tank?

Thanks for the links and advice Cmor.

Innovator: I have a desjardini sailfin, starry blenny, and a mated pair of false clowns.

When I say that Naso has ich, it really has about 5 small spots on one fin and 2 on the other. My concern isn't really the ich right now. The sailfin had a few spots on his caudal fin, and they disapeared in a couple days. I know its a threat but with the parameters the way they are, the fish eating everything in sight, and the help of a couple cleaner shrimp; everything seams to take care of itself. I still plan on setting up a QT tank for the current ich issue, and I appreciate the help.

The markings I am talking about right now are hard to explain. Looks just like the other Naso's I've seen with some scrathces on them, but mine covers a lot more of his body. He swims right up to the glass when I come up, so I have been able to stare at him inches away. There is no raise on the markings, and they are almost reansparent when he changes into his light blue color. Looks like it could even be a little sting form torch coral or my elegance. Don't know what that would look like, but it's an idea. I was hoping someone would tell me they have had something like that with their Naso more than anything. IDK, I'll keep you guys posted. He is very happy, active, and hungry for now.
