some type of sponge?

This has been spreading. It has yet to leave this rock. It clearly originated with the hammerhead frag.

It is growing out in strands with several of these, I don't know, "spikes" sticking out of it...

I am slightly concerned it will bother my coral, but my hammer doesn't care at all about it...

Also concerned of it taking over.

Thoughts?









as compared to this sponge I have on the other end of my tank

 

Looks like a sponge to me, as long as its not bothering anything leave it be they are awsome filter feeds and help keep the water cyrstal clear.

 

I have a bunch of those on my live rock I bought today and the guy at my local fish store told me they are just sponges (I was worried about them too). They are cool!

It is a sponge what type i am not sure i have googled the heck out of it with no possitive ID... I do know i have had that type in my tank.. and grew quite fast in the shadows so to speak in the live rock...


Best of luck...

 

Ok a pot of coffee later this morning and this is the closest i can come to a ID... I am sure i am wrong but i am comming out swinging for a ID for ya...

Look for Leiodermatium in the sponge section...
