Something is propagating in my tank

Can anyone identify these growths? I think if I don't do something it is going to over run my tank.

@KJ
#reefsquad anyone have any ideas?

Sponge.

A little fuzzy and far away, but I'll guess, starting on the far left and going right

1. Aiptasia
2. Don't know
3. Nudibranch
4. Don't know.

Bottom line, need better pictures.

+1 for sponge.

 

[cronosx99]

What can I do to remove them if they are what you believe?
Will take better pictures later
Thanks

Sponge is a good sign of a healthy tank. If they become a nuisance you can easily brush them off.

Hopefully more easily identifiable

Pineapple sponges. As your tank matures their numbers in visible areas will diminish. Totally harmless.

Thanks, my tank has been cycled for almost 3 months. Thought I had some sort of parasite

They also like lower light conditions, only place I see them now is in my overflow and darker portions of the sump. Completely harmless filter feeders.
