Help my loved fish is sick

[HimSelf]

Help everyone my black and white saddle back clown is sick. My girl friend just noticed tonight that one of the eyes is swollen (like this ) and the other one looks a little bite big as well. What is wrong? How can I cure it?

The only thing I can think of is the clown had some sea weed this morning and that’s it.

Help please; my girl friend is going to force me to take down the tank if her favorite fish dies .
