Clownfish puffy mouth?

[dannyboy1302]

Hey guys got my clownfish a couple days ago, the first day he was eating fine but now he's not "/ his mouth is slightly open and a little white, should I return him to the store??

I doubt they will take it back, but you can try, they may give you a store credit. The clown is not eating at all? No aggression between the two clowns? Has the new clown been mouthing corals like Frogspawn (the Euphyllias)? If possible an image might help.
