Martin,
Check some of the reef aquarium sites. I don't know if you will get an
exact identification, but these little stars are common in reef
aquaria. They typically have 6 or 7 arms and generally stay very small,
no larger than what you see now. They probably do no harm but if they
start to get too numerous you can remove them manually. There are
probably more than you see hiding in the live rock and sand.
