    does this mean it's dead/on it's way out?

    also found this hitchhiker:

    First 2 pics are of a peanut worm - Sipunculus nudus - they enjoy burying themselves in the sand. No idea what the black thing is, if you check in the ID Needed forum I am sure someone else had something similar and sihaya identified it as a good guy.

    Thanks viper. Is the peanut worm ok to have in my tank? Coming out of the rock, does it mean it's ok and not dying? watched it for about an hour this morning, very little movement, not sure if the current moved it or if it moved by itself?

    They are completely harmless and very useful detritivores, very good guys. :)

    It could be a bad sign if he's not moving around, they tend to react very quickly to light, if it's night time and you shine a torch in the tank then they retract very fast, try to put him on the sand against some liverock in a spot in the tank where there is very little flow, let him choose if he wants to go in the rock or the sand, hopefully he will move and bury himself.

    I'm not sure about this but they could be nighttime creatures, so perhaps that's why he's not moving, because the lights are on?

    Looks like some type of nudibranch (sea slug) check here: http://en.wikipedia.org/wiki/Black_nudibranch

    "The black nudibranch, Tambja capensis, is a species of dorid nudibranch, and is only found in South Africa. It is a marine gastropod mollusc in the family Polyceridae."

    No problem. Good luck with it. From the little I know some of them have special requirements for food and some can be toxic so do some research.

    Have seen these guys in Balito and always wanted to keep them, but they are specialized feeders and would not survive for long in a aquarium:(
