Ok, I just noticed this stuff starting to grow on my rocks in places. It looks almost like a slimey web/coating over the rock, and there are little tunnels in it. What creature made these? and if it's something bad how do I get rid of it?

Sponge.
 
:iagree:

as such creature
 
I think its some type of encrusting sponge As to what exact one I will need to look into it a bit more.
My best guess is a leucandra aspera.
(Psst, that would be "colonizing sponge". Being as their bodies are soft and fibrous, they are incapable of 'encrusting') -Em:)
 
OMG i have that TOO!!! i was wondering what that wierd thing was growing in my live rock... i thought it was like a brocken foot pedal of an anemone that has left there adn wudnt come off... i was too lazy to try to remove it.. i was thinking a sponge would look more something like umm one of those sponges that are used for hermit crabs... yeah this is my first time seeing sponge on live rock before...

and umm im gueseing this sponge on the live rock is a good thing right?
it wont take over my live rock and like completely cover it would it? cuz i prefer the purpleness of the coraline over the sponge =D

lol I haven't covered sponges yet in zoology it was a guess but I have never seen a colonizing sponge that looks like that though.

wouldn't colonizing sponges be a group of seperate genetically different sponges?

at the very least this is an encasing sponge.. though crusts can be soft and, for lack of a better word, spongey
