Yet Another Moorish Idol Thread

[straightrazorguy]

After eating like pigs for a few days the idols stopped eating. They were hovering near the surface breathing rapidly. I did a 30% water change and lowered the water level in the tanks so they get more oxygenation (the hang on back filter is the only turbulence they get). They seem to be better, but they are still breathing rapidly and not eating.

Any ideas? Suggestions?
