clownfish mouth stuck open!

[AlaskanDiver]

I have had my false percs in my 120 gal mixed reef for 6 months or so. They have always been fine. Recently (past day or so) i noticed one of the two fishes mouth is suck open! She can't seem to close it! =( the only thing that has changed is that they pair started hosting with the large hammer coral this week. They have both been in the tank (hammer and fish) for a few months, but the clowns decided this week it was a good place to set up shop apparently!

I just did a 20% water change the other day, and tested all my parameters tonight. Nothing out of the ordinary there... Nitrates/nitrites=0, ph=8.0, alk= 8 dkh, salinity 1.025, phosphates=0, ammonia=.25;

Any ideas?? what can i do to help her??

I think i am going to run carbon for a few days, see if there is anything i can get out of the water maybe.... =(

i feel so bad!! she looks so uncomfortable! she can eat, just not as much as she could/did before the mouth thing...

HELP PLEASE!!! =)

I wouldn't be too concerned if her behavior hasn't changed since you noticed her mouth agape.

As long as she is eating I would imagine she will be ok.

Seems to be pretty common. Apparently clowns are not very smart. I know my Maroon about killed herself trying to stay in the colt coral. She eventually one, but I wasn't sure she'd make it.
