    What is this guys? A star? It is about a pinky nail size, moves around but how come 2 legs are thick and the other 4 thin and short?

    Hello Tobes! Yes - it is a star-fish - BUT A VERY BAD KIND! It is known to prey on soft-corals.... I would remove this star-fish immediately from your tank. I cannot remember the name - BUT I know that this is a bad kind of star....

    Rather take it out and either place it in the sump (it would most likely die), or (preferably) take it to your LFS....

    Hi Jacquesb, would appreciate any more info that you may have on that starfish - they are extremely common on the breakwaters at Durban harbour and I have been trying to find out more about them. Thought for a while that they were just juveniles that were somehow deformed until it became apparent how common they are there. Thanks

    Easy boys, that is a very innocent little Asterina star fish, a detrivore, totally harmless, could possibly breed a bit much but other than that, about as dangerous as aneutered mouse

    I would have to agree with my learned Muppet like friend here, saw them in a John dorys(PMB) tank with some great soft corals in

    Actually you are quite correct, they will eat dead or dying polyps as the are detrivores.

    They actually reproduce by "losing" legs and the leg grows, thats why you will see 3 legged, 4 legged, 5 legged and 6 legged ones;)

    Also check out WWM about these.

    In all fairness some guys think they do in fact eat polyps, however it seems they just got a raw deal because they do eat dead polyps, I speak under correction but I think Alan has a few in his tank

    Think that your link refers to a different species Kanga. I have asked a friend of mine to ID the animal for me and will post the identification. Life history is probably pretty much the same though from what I have seen the animals do.

    OK - I must apoloigize - I could have been too hasty. BUT, even though I am quite positive that you do indeed get a predatory species of star-fish that looks EXACTLY like the one in the picture. Asterina too looks like the one in the pics - I just remember the one "leg" being longer than the other 4, on the predatory species. I will research some more and post my findings.

    Ok found the following:

    Howzit guys, back from JHB. Thanks for all the info - quite an interesting read. I saw him ate some white stuff underneath the live rock the other day, didn't see him on my polyps yet.

    Hi Tobes - cool! Perhaps just keep on monitoring the situation - as soon as he is on your polyps, or your polyps sees to be suffering in any way, then take it out of your tank.
