Naso Tang with skin discoloration spots?

Hello everyone,
I just bought a Naso Tang about 4 inches long along with 3 other fish (Blue Spotted Jawfish, Green striped Mandarine, Niger Trigger) he was very healthy and colors were beautiful. He has been shy and has just now come out to eat, I have a lettuce leaf that is in there and he is eating it every so often while my yellow tang is picking away at it.
Anyway's he has been doing well and shows aggression sometimes towards my yellow tang and then just today I saw that he has some skin discoloration in the middle and lower side of his body. There are 2 ovals that are lighter with a dark border. One of the spots has a white skin piece it looks like protruding from his body just aft his fin. He seems to be doing fine but I am worried what that is.
To me it looks like some sort of skin disease or maybe my yellow tang cut him with his caudal bone.
I will try to upload a picture of it as it is hard to describe, but in the mean time any help is appreciated.
here are my tanks specs.
70 Gallon tank
100lbs of LR
30lb of LS
Salinity 1.026
Temp 78-80 F
2 x 150w halides 15k

Can you post a picture of the problem? How many days since you've had this fish?
Lettuce is not a good choice for fish. Algae sheets are the appropriate choice.
Also, bad news...a 70 gal is not big enough for one tang let alone two. Aggression will only escalate. Neither tang will do well for long in a 70 gal.

I will try posting a picture, I have him for 3 days now. He is eating fine. BTW Why not lettuce, my yellow tang loves it.

Id say thats still a little high. Well in the wild lettuce would not be found in there regular diet. I agree with beth I recommend using the algae instead.

Well lettuce was fine 3 years ago when I was on these forums (just got back on today). And I was told from the start to have higher salinity in a reef tank.
My my things have changed haven't they...

Sorry if anyone got bad info about lettuce on this forum. But lettuce is about like eating nothing, meaning it has no nutritional value for marine fish. It adds nothing, giving them nothing of value nutritionally. On he other hand, marine algae sheets are on the menu for grazing fish.
1.025 is about as high as it should be.

Sounds like your friends are giving you some bad advice. Were just trying to help but I guess thats not what your looking for. Maybe your friends should start their own forum if there so smart or maybe write a book on their philosophies so we can get a good laugh.
