issue with naso ... help
 

:cry:

Our naso seems to have a weird white patch on his side..
I suspect it to be a fungus from a battle with another Tang in the tank. can anyone confirm this for me, and possible provide a good treatment :)

Do you have a QT? If not you can feed the fish food soaked in selcon and garlic extract (garlic extreme).
You need to know that naso tangs require brown algae as part of their diet.
Have you had this tang for a while because generally they will not fight each other once they are used to each other unless they are crowded.
That is a lot of fish in your pic. Are you sure you are not overstocked and this is a water quality issue?
Have you lost other fish recently?

they are all fed Brown, red & Green algae on a daily basis. But i will start adding the garlic to his foods

knock on wood, no i have not lost anything from this tank in years. The naso & powder blue are the newest addidtions. there was a little scuffle for the first day, but now they all seem to get along. except the clowns. they attack anything that goes near them... :)

The best is garlic extreme from the LFS or garlic extract from a health food store or squished garlic. The rest of the stuff is simply watered down garlic juice.
It has anti fungal and parasite properties and are especially good when you add a tang to your tank because as you know they are ich magnets.

Looks remarkably like a piece of coraline algae....

Ha Ha I thought the same thing.
