    Hmmm... a starfish normally has 5 legs.

    My guess... Luidia maculata

    You say there were lots of them together. On what were they? Just on the rocks? or within some corals? Might help to work out what they were eating to work out if they can stay in our tanks.

    But at the size mentioned, 15cm. That is big. Even if they are algae grazers, you need a dirty BIG tank.

    just on the rocks...it had seemed that someone had turned a lot of the rocks over and some of them were trying to get back under and most were just moving off to deeper water...wish I had a camera and could've taken a pic

    Yep, definitely a predatory species. Most have 5 arms. I believe it's also a cooler water species at the northern end of the range, because they're very common in EC and less so in KZN. Probably not ideal to keep at full tropical temperatures.
