Hope this is a better picture.
Anyway to help with how it looks. It kinda has a brown surface with white spiny things coming out of it. These are quite small and you really have to look to find them. The white things look almost worm like (but are not worms) and have tiny tentacles on each of them. Tried brushing against it with a net. It didn't really retract.

I'm not sure what the brown stuff is, (algae of some sort perhaps) but the spiny things your describing sounds kind of like spionid worms.

Don't spionid worms have a tube they live within?
That's what I fear. I have digitate hydroids in my tank. These are not digitate. Could these be colonial?
Hmm any suggestions on how to irradiate this pest?

Nudibranchs and certain type of snails are the only natural control I am aware of. Unfortunately, none of them are readily available. Worse, you need to know the exact spices of the hydroids (which we are still not even sure) in order to find the right nudibranchs. For example, certain types of Opisthobranch sp. will almost certainly be able to control most hydroids you throw at them.
In all honesty, manual removal is probably the only and best way to go. If this is the only patch you have, just physically remove this particular section of the rock and be done with it. If you are able to make sure to keep nutrition low in your tank, it's possible they never become a real problem.
