Hi everyone. It's been a while since I needed help again.
Recently my tanks been growing this strange thing on one of the live rock.
and I have a lot of this pod looking things growing in under lite places. The first one started as a blob on the rock and sprouted three stalks. The second picture is of the infestation of what looks like sponges or something like that. Please help me with theses.

Is it good for my tank or should I worry about it?
If It's not a good thing then what should I use to remove ot kill it without hurting my fishs?
I have a Yellow Tang, A sail fin tang and a tomato clown 3 turbo snails and a brittle star fish.
I would really like to know more about what type it is.
 
I can't tell you the scientific names of the sponges other than that the 2nd pic is of a pineapple sponge. They are both a sign of good water quality.
