Mouth rot french angel

[Rossf1]

Hello,

I am having a problem with mouth rot and what appears to be ich on my french angel. It started 2 days ago. He is not really eating today. The reason I said ich is i see some spots on him and now on two ther fish. What can I do.

Tank setup is as follows
150 gallon
Aqueon 4 proflex sump setup with refrugium in center chamber, uv steralizer in sump.
Live rock and live sand.

We have one anemone and two or three coral frags nothing expensive as far as coral a friend gave me a few frags to try out.

I can't treat with coppersafe, Imhave no idea what to do to keep this fish alive and not have this spread.
Looks like that coliminurs disease.

My local fish store told be to try kick ich, did first dose yesterday, was told it is all I can use that won't kill my rock, sand, etc.... Or ich attack. I chose kick ich as I saw some people post they had positave results with it.

You guys are the experts, can someone please help. Imhave no qt tank and even if i took out the few fish infected wouldn't the bacteria or fungus still be in the main tank.

Help?

Thank you

Ross
