My guess is that they're offspring of my red starfish that recntly died, or they're urchin babies. The kicker is that they have six legs, my red star had five. They could be brittle stars that came in on new stuff.
Will you guys let me know what you think?
Here's a pic from my phone, hope it turns out...

Looks like astrea stars. Ive got thousands of them in my tank. No harm to sps lps or softies. most of them are harmless algae grazers only a few species actually fo after sps.
