    Hey all

    I noticed when i added my live rock 2 weeks ago i started to see bits of life. However, there has been a white starfish quite small - probably size of a 20c piece but i haven't seen it again. However, this weekend i saw the critter below - size of a 10c. Different to the first and the first didn't have spiny legs as this does. Anyone have an idea?

    From which country did ur liverock originate? Normally,the little white stars can be asterina stars,but the spiny legs on this one,i am afraid to say crown-of-thorns(baby),because thats the only star i know of with a lot of spines. Any starfish experts?

    Closest id i can get is a juvenile comb star,only problem is that comb stars have 5 legs,yours got 6. Now if a star has 6legs,it can belong to the echinaster family. Do u have any more pics of it,maybe from the top?

    Hey frankie - that was the best shot i could get at the time. I will see where it is this afternoon/evening and if there is a better shot i can take i shall do so.

    As i said it's the second star i have seen in here. The other is either "gone" or hiding. That one had 5 legs - long and thin and also white but was a little bigger.

    If u look at the length of the legs in relation to the body,it may be a brittle too.

    I have to agree with some of the above mentioned posts...looks like a Brittle Starfish...

    Class: Ophiuroidea

    Just make sure it is not one of the "larger serpents"...if you look at the oral disc in the center...you'r star's disc sure looks big in comparison to the overall body picture I posted...as you know the Green Brittle can go for small fish...I have to state...purely if underfed, but what I want to say is the fact that they have the "bigger oral disc"...and if I'm not mistaken, could you'rs have too? Unless the legs just gets longer and the body grows slower...?

    I will definately keep an eye on it. If it grows and is suspiciously like the green brittle I will get rid of it - humanely.

    Thanks again.
