clear green brain with tubes inside

[wanabesalt]

i have a clear green brain and a clear brain attached to some live rock .......they both have tubes in side with holes coming from the tube to the out side does any body know what they might be.

might be polyps. I have similar. they are just young and should develop
Do they look like the bottom right hand side?

 

[paulcoates]

that not a great pic, but I still think they are probably young polyps

yea they are so small the size of a pea and the clear one is a little bigger ......so polyps are in clusters to......from what i see the the hole opens and closes i guess each polyp. i thought polps were individual..a single polyp
