Percula9,
We frequently see supersaturation in aquariums. All it takes is for a person to forget to top their sump up, and if the pump is powerful enough, when it catches air, the tank can supersaturate. Leaking fittings can also cause it. There is also an issue with supersaturated tap water in northern latitudes in the winter, but that is too complicated to describe here (Hemdal 2006). The gas bubbles come out of solution behind the eye and exopthalmus results. Myco is HUGELY common in aquarium fish -
I have no idea what you meant about sending histo samples out, but that and culturing is what you need to do to positively diagnose it.
I was not bashing you, I was pointing out that you have a habit of giving overly short replies to what can be complex issues.
As for my helping bulldog - my first post gave the follow-up questions, and he/she hasn't responded. I can't help until then.
