What are these orange tentacles?!
 

The ooze out of my one piece of rock every now and then... the whole rock is about the size of a tennis ball, and these guys are about the thickness of those annoying plastic things that hold tags on to new clothes...

btw this piece of rock came from a LFS display tank!

Spaghetti worms. :)

+1 Which BTW are a good thing.

+2

thanks for the replies.

I thought spaghetti worms were transparent; I do have some in the same rock actually...

I flipped it up btw, these suckers are pale orange and pale green... also, there's like 6 or so coming out of the rock...

oh well.. I SEEM to remember something like that wayy back when I was in HS and had my first reef (lmao, I am sick, never mind)... but one of the crabs made quick work of it

They can be anything from beige-y tp green-y to red.

pheww
 

ok, good to know it's a worm of sorts then... it will stay I suppose...

speaking of which, I caught my spaghetti worm (its neighbour) out this morning, since the tank was in the dark... nasty little bugger... a weird earthworm kinda look... he crawled back into the rock as soon as I turned the light on... so yeah, I woke up the fish (Xavi)
