These 2 popped up today. Should I get rid of them or are they safe?

Asterina starfish. Some are safe and some like coral. Any we see got removed as they can spread quickly. We unfortunately had zoa eaters and their was no way to tell the good from the bad.

They are Asterina starfish. Still up in the air if they are safe or not.....I consider them an important member of my clean up crew. They will multiple like crazy though by dropping legs. I normally pick all the ones out each week that I can see. If you see 2, you probably have at least 20
