Whats wrong with my fish

[KrazyKuch]

Hello all, I just bought a Signapore Angle (sp?) yesturday and since I have put him in the tank he has just sat in the corner breathing kinda hard...won't eat anything nore will he leave the corner....It looks like his one eye is bulging out further then his other one, although when we bought him his eyes were fine,I think it might just be irritated...

So is he just stressed and needs some time for his eye to go back to normal.Or does he have some illness and might die from....I have the option of returning him but only untill tomorrow night.....

Anything I can do to make him get better??
