Clown eye's bulging-Terry B. or Beth?

[phishy]

I posted this in another forum and was told that if I posted it here Terry B. or Beth may be able to help me out.
I recently noticed that the eyes on one of my perc. clows were kinda bulging. The other one is fine...as well as all my other fish. I have tested the water and everything is normal. Any thoughts on what this could be?

Basically caused by an infection or injury to the eye. Is this a new fish? Have you netted the fish lately?
You can try a water change to see if the problem goes away. More likely the fish will need to be treated with an antibiotic. Maracyn Two for Saltwaterfish. This medication should be used in a QT only.
You can also try some heavy feedings with garlic. Use fresh garlic and mince it in a deadicated container [retaining the juice] soak frozen or fresh seafood mix [receipe in FAQ Thread] for 1/2 hr in the refrigerator. Garlic has a mild antibiotic quality.
Worse comes to worse, you will need to QT and treat with an antibiotic.
