Hundreds of baby snails.. urchin and a starfish?

[Nate_Krohn]

I woke up at about 2 am to enjoy my tank when the lights go off and there are hundreds of baby snails on the rocks and on the glass.. I also saw what looked like a baby urchin and some type of starfish. Can anyone help ID them?? I posted some pics. They’re not the best because they’re at night.

That last one is an asterina starfish. They have mixed reviews among reefers, it really depends on the specific species. There is a chance they could start eating corals. The ones in my tank look similar and to my observation haven't touched any of my corals. They will start to multiply like crazy so remove it if you don't want potentially hundreds of them.
