Help! Female clownfish dying!

[ironman187]

Hey all, I just walked by the tank and noticed our female clownfish lying on the sand breathing heavily. I literally just fed her not too long ago. She was fine and active. I don't know what would have caused this since all the other fish in the tank are fine, and she has no visible wounds. She is currently in a floating fry tank lying on her side.

What other symptoms do see on her?

If nothing visible on her, I can only suggest checking water parameters.
