Is this alge?

Looks like a sponge covered in cyano.

 

[The sculpin]

Hmmm? I do have a little cyano in that tank. I'll try blowing it off with a turkey baster.

 

[The sculpin]

I blew it off and I think you are right and I think the cyano killed it

I think its great you would consider doing that for a coral
