I agree with Fluff.

really?? even the green? wow, i thought it was some kind of algea or somethin. good then? no special care?

 

[melosu58]

I agree as I have them all over the tank. Just harmless filter feeders

i have those yellow one's all over in my 20gl, they add some nice color i think.

Yep.
I've got a 3" or so, pink sponge growing under a ledge with the same "breathing tubes" as your green ones.
I was worried too until I found out what it was.

I believe the yellow things are actually trunicates of some kind. I have the same ones in my tank and they are not structured like any of the other sponges. Maybe a different animal though. Mine retract their siphons when touched.

They are sponges. I have them in my tank all over. But, here is a page from Bob Fenner's site with these exact sponges. Second one down I believe, and he is agreement that it was a sponge.
