Percula Clown Diseased?

[FLcracker94]

I've noticed for a couple days now that my Percula clown is acting a little weird...I'll walk into the room and see it sortof leaning to the side, eventually going upside down, then back upright again. I think it might be Swim Bladder Disease, because it says th symptoms are loss of balance and/or abnormal swimming. Is this disease lethal to the fish, or will it just make it look goofy and clumsy?

All I really need to know is:

Is it Swim Bladder Disease
can it kill the fish or is it fine

Likely swim bladder disease of some type and these are usually fatal to fish . You can try medicated quarantine treatments but these rarely work.
