    I was looking at my live rock to see if anything new showed up, because it's a newly established aquarium. I noticed something weird and green with tentacle like things. I can't really tell if it's moving with the current or moving on it's own so I really need this thing ID'd so I can remove it right away if it's bad. Please help! :confused:

    Here's a link to the video (Change quality if it doesn't start in HD!):

    Hi and Welcome to 3reef.

    I saw this on ReefCentral, but I can not view the link here.

    The angle and distance in the video make it hard to tell. If I had to guess based on the coloration and what little I could make out I would be inclined to consider a Spaghetti Worm with it's tentacles drawn in.

    Thanks for the welcome, and the reply!

    I just edited the post, I accidentally added the wrong link when I posted it! xD

    Okay, I'll go ahead and research the Spaghetti Worm to see :)

    Other people were saying it was a Lettuce Nudibranch, but I don't think they have tentacles like this, do they?

    After viewing it again I would say Nudibranch of some kind is probably correct. Nudibranch come in all kinds of strange shapes, colors, appendages......

    Haha! I bet! All these inverts look like a bunch of little aliens. xD

    I've been looking all over the place, but I can't seem to find any invert with this coloration. A green body with yellow tipped tentacles. So it could be anything! And I think there's actually two in there because I managed to gently nudge it with a wooden skewer and those other tentacles didn't move with it.

    Nope, the only living things are three hermits, one turbo snail and the "live" rock. Although I did add a Xenia which sadly perished due to the tank being way too new and the water quality too clean. But may I ask why you ask?

    Nudis usually come in with something they look like I bet this one eats GSP, though it might be a herbivore

    Oh okay, makes perfect sense. It seems to like the purple algae because it hasn't moved away from it. But there could be some green algae on there that I can't really see well.

    I couldn't see the video originally, but I can now. I've never seen them in person, so I haven't seen them feed, but it looks like it might be a Melibe species, which is a specialized nudi with a "cast net" on the head. Check

    The Sea Slug Forum - Species List

    and scroll/page search for Melibe. It looks like he's extending his oral veil to me??

    Cheers,
