kole tang issue!!??

[johno4]

I posted this in the fish only section but I probably should have put it here as well. My kole tang seems to be unable to close its mouth. I purchased him yesterday from the lfs, he was fine there, put him into qt and notices his mouth is stuck open. have a look at the pic in the other post and give me your thoughts. Is this a normal stress induced response or is he in trouble? He has not eaten anything since if bought him yesterday.
