Dwarf lionfish sick

[icereefer]

Hi
I was wondering if anyone could help me help a reefer friend out. I'm not much up on dwarf lionfish, but I have to do what I can to help a reefer friend of mine out. plus I know how much he loves his lionfish.
he sent me some pictures sorry there the best he could get.
okay from what he's told me ,his lion hasn't eatin in a week now and normaly, his lion is like a puppy dog when you get close to the tank and he thinks it's feeding time it will come to the surface and spit water at you. and he's saying now it just doesn't respond when he goes up to the tank and won't eat.
it's got these bumps like white zits on his cheek and the bottom of his mouth. his noticed it a few days after feeding him some squid he got from the grocery store, I was thinking it could of been chlorine burns from the store bought shrimp, but his maroon clownfish was eating it to with no side affects.
any help would be great of you.
I'm posting a few pictures he sent me in hoping someone has see this before.

PS could this be the start of cauliflower?

Someone here might help if we could get some more information:

Just what has the fish been eating? (Please clearly list it all).
How long has your friend has this fish?
Water quality and parameters?
Was the squid fresh or frozen? Had it been frozen before the store thawed it? Have the foods been fresh or frozen in general?
Was the fish quarantined before it was put in the display tank?
What other fishes, inverts, and livestock is in with this fish?
What kind of system is it in (FOWLR, reef, etc.)?

The spots, as far as I can tell from the photos, doesn't appear like the Lymph I normally see.
