sick clownfish

[Baldy]

Hello,

I have had 2 true percs in my 75g for about a month now, and just yesterday something strange started happening. They used to swim together, mostly hanging around the top of the tank, but when I got home from wit yesterday, noticed they were both in opposite corners, at the top of the water. Not very active, just kinda sitting there. The female looks ok other than being very sluggish, but the male has become very bloated. Both ate yesterday, although not as excitedly as they usually do. Then they sent back to there corners again. I got my girlfriend to check on them at lunch today, and there is no change.

Nothing in the tank has changed other than I've been feeding them enriched frozen brine more lately. All water parameters are fine.

Any ideas?
