Help! Do you know what this is?

[Noah123]

Help! I have no idea what this is, I noticed it growing on my live rock about a month ago and almost thought it was a coral but then I was told it might be some kind of macro algae. Any information would help me out, especially on how to take care of it. Thank you!

Are the leaves thin/flat, or fleshy/jelly filled?

 

[Noah123]

They are fleshy/jelly filled

 

[tektite]

Possibly a type of Predaea.

 

[Subsea]

If rock came from GOM, I would say it is Nemastoma or Halymenia Elongata. Both are slippery and jelly filled to the touch.

By the looks of it I'm pretty sure it's Nemastoma, do you possibly have any information regarding how to take care of it or of it likes water movement or not? Thank you!
