What are these growing in my tank

[Badgers reef]

Have quite alot of these little buggers in my tank they look like little cucumber green spikes on its back moves like a snail they keep going all over my zoa's which is stressing them slightly?

The only thing green I see is the zoa. The outer ring is called the skirt, it's part of the coral.

That is a zoa eating nudibranch. Notice how it resembles the zoas that it is on. That's because that's what he eats, and that is his camouflage.
Pull it out!!

There are loads of tiny ones any suggestions to get them all out or just pull them all out?

 

[Flreefer]

I'm not sure of any predator of them, just pull them out as you see them. They shouldn't stray too far from their food source.

Ok thanks i shall start to pull them out as many as i see daily hopefully after a week they are gone
