Whats Wrong With My Clowns

[bpoore89]

I have a 55, with two clowns and a yellow tang. I was away from home last night and when I came back this morning, I found all my Kenya trees closed up very tightly, and my two mated clowns where seperated and hanging out under diff caves. The female is kind of sitting on the bottom but is still "waddling" like clowns do. Im worried but I have no idea whats going on. The tang is perfectly fine and swimming and eating like she always does. The clowns wont eat. I did a 10g waterchange just incase. Ammonia, Nitrite, and Nitrates are all undetectable. Any ideas? Thanks

Have you checked the temperature? Perhaps the room temps dropped last night and your heater isn't keeping up.

Temp is at 80. I know its puzzling me to. Im skimming wet just to try and pull out anything i can
