Urgent help please

[Coralgurl]

Yesterday I noticed my male clarkii fins appeared to be a bit tattered but he was eating fine, so thought maybe my female was messing him.

Tonight he's hiding in a corner of the tank he never goes to, his dorsal fins are basically gone (along his back), and he has white spots on him. Last night he ate like a champ, tonight nothing. Will post a pic ASAP.

I don't think it's velvet from what I read, with the fin issue it's not ich.

What is this and what do I do?

The photo is not great as this side of the glass I don't clean.
