It could be caused by a couple of things. An abrasion or some trauma to the eye, or it could be a bacterial infection. For an external problem, like an injury, Mela-fix should do the trick. For a bacterial infection, Maracyn Two works well, but should be double dosed for one week. Do you have a separate hospital tank you can use to treat the fish? Is the eye cloudy? It does sound like pop-eye. I'd try the Maracyn first.
What is Maracyn and where can I get it? Can I treat it in my tank or do I have to seperate it from the rest of the fish? Also, Tell me more about Mela-fix. It looks like the fish may have a scratch and his eyes are cloudy.
I think it erythromycin. Anyway unless BOTH eyes look bad I would say it is almost certainly the result of an injury rather than infection (although it could have a secondary infection). i would not medicate your main aquarium, and I would not move the tang but rather feed him high quality food, do some partial water changes, and let the healing process do its thing. I've seen a couple eye injuries on my purple tang go away within a week.
Hi :
Yes erythomycin is maracyin.
However, SW Maracyin II is slightly more effective, its minocyline.
However do a few other things first.
1)- do a few water exchanges to ensure that your water paramters are not off and causing the problem. 2)- after your water changes , give the eye 3 days if it doesn't get better then treat the tang in a quarentine tank.
I use either SW maracyin II or Furan2 both work (for me furan2 works better and faster-but either will work).
Is the eye clear or cloudy and or red?

9 times out of 10 popeye goes away on it's own, it's almost always stress related.. either physical trauma or environmental stress. If conditions are good and you can rule out environmental stress and it doesn't improve, you can also try soaking fish food in antibiotics, especially if he's too big to quarantine (don't know how big he is).
Speaking of vlamingis, I've never had a faster growing fish.. mine is a garbage disposal and is growing at an amazing rate. Going to be a foot long soon, and he was less than 2" a year ago.
I've treated fish with this problem several times, with 100% success;
1 - Takbe a bowl of fresh water in the same temperature and pH of the aquarium. Better if you have RO water. To adjust pH, just add a little buffer to it.
2 - Add a tea spoon of methilene blue - the salt - to the freshwater. Ít will look loke a bowl of ink.
3 - Put the fish in for 10 to 15 minutes. Large fish for long time, small ones don't do very well after 10 minutes.
Bingo ! Eye normally comes back to crystal clear in 24 hours. Repeat bath in three days if necessary, not less.
As i mentioned I would just ensure your water quality is up to par, and then if the cloudiness doesn't go away consider treating the fish. However make sure the waters paramters are excellent and theres no major harassment by tankmates.

Interesting observation. My vlaming is going on 9+ yrs (I got him in '92 as a 2" pipsqueek) and nows he's (she) is a little over 1 ft. The growth rate has been pretty slow, I would guess almost 1/4" yr for the past 2 or 3 yrs, but what is really noticable is the flattening nose and the elongating fins. Hes been in a 180gal since 95. Maybe you'rs will slow down. Your right garbage scow and very territorial
Be interesting to see. He's in a big tank.. 350 gallons, but the tank is 8' long at it's longest and 5' wide at it's widest.. alot of swimming room. Even when it was in my 90 it was growing a a good pace, tho not nearly as fast as it is now. The nose is already starting to get that vlamingi look, and there are tip points on the tail now. Fish has awesome personality, it's fearless.
