great thanks you. So eating the Dino's is a good thing but may turn on coral if they get hungry ?

I would get rid of them. I've had them munch on zoas

Asterina starfish. I have some in my tank...the white variety, they do not harm my corals and they help clean the glass. They can overpopulate very quickly so I remove them if I can but not a crisis I don't think UNLESS they are the blue or pinkish variety which are known as coral munchers

 

[Rarend99]

I must've had one of the blue or pink ones because he made lunch out of my zoas

Most likely....those I would remove asap

I've been noticing some zoas on the sand bed have been looking horrible while others on rocks are looking great. I'll start removing just to be cautious.
