Something eating my Toadstool? New pic

Thanks for the info guys.

I removed the Nudibranch.

My only tought is: You can see the worm always right where the flesh of the coal is being eatin away, as you can see in the picuture. So i am not sure is the worm bad and eating the coral or was it the Nudibranch who was under the rock not even close the coral?

 

it was the Nudibranch, also look out for eggs on the coral

 

Kill it with fire....aka dip the toadstool in Coral Rx.

 

^HA! I sucked him out last night, will flush him tonight. I will pick up some Coral RX and dip the coral to be on the safe side.

So everyones thoughts are the worm is reef safe and actually good?

 

If it's a sipunculid it is, and it looks like one. Sure is in a classic guilt-by-association position, though.

 

Yes it is.
