Star fish ?

[dakesojo]

Hi
Can anyone advice on what this is, I would say a star fish but I am not sure as I have counted 6 legs.
Thanks in advance

Looks like an asterina regenerating a leg.

Asterina starfish. Some are good and some are bad. They can populate a tank quickly.

As above, Asterina (Aquilonastra) sea star. They normally have six arms, but when they get about the size of your pinky-nail, they rip themselves in half. Each half then grows into a new star, and repeats the process.

Most are (mostly) harmless, feeding on coralline algae and biofilm, but some have been reported to consume zoanthids, as well.
