help identify...pictures

I wanted to share some pics, I also had a question for two things. One what leather is this in the pic with the yellow watchman and I also added a pic with a green circle around something that has grown in my tank. It's only on one rock, it's got a rubbery texture beige in colour with some darker colour on top of the beige. If I try to remove it it feels like rubber and breaks in pieces?

 

The first one is either Sarcophyton or Lobophyton(leather). I can't see the other picture taht well to address the id of what you are talking about!!!...sorry
Maybe you could take another picture!

 

Ok I'll post another pic later. thanks.

 

Nice pictures

Are you talking about the jawfish or the watchman. Either way both are amazing fish to have. They have alot of character. My jawfish eats from my turkey baster...it trusts me more than anything in the tank! My watchman is still really small and skittish.
