Identification...

[Yellow Eye Tang]

Hey all,
Ive been noticing the last week or so im getting a growth on some of my rocks that looks new. Its a white transparent worm looking thing, but im getting them in a few different places. im just heading out for work and thought id ask around. Heres a couple picturees and it seems i cant get the best shots of it but these should do. If you cant see them good enough ill try again when the lights a little better. Anyways if anyone knows id love to find out if this is ok to have in there. Thanks again------------ Llegolis

I have a lot of this stuff under my rocks. I believe its a kind of encrusting sponge. There are little tubes or spouts coming out of it. Only grows in low light. Harmless.
