True Perc W/ Open Mouth

[DidYouSayReefer]

I recently got a frogspawn and my true perc started hosting it imediatly. He does not leave it alone. I noticed that the clown does not shut his mouth and it seems a little swollen. There is no discoloration. Could the frogspawn be stinging the clown or is this some disease? I don't have any pictures and I have had the frogspawn for about 4 days before this started happening. It looks like the clown is OK other than the stuck open mouth and he still hosts the frogspawn. Any ideas?

Is your percula still eating?

This happened to my clown when he discovered the frogspawn. he would suck on the tentacles and get a swollen mouth for a couple of days. The swelling went down and he was fine
