Eggs... what the heck are they?!

[Mayadana39]

Hey guys, pretty new to reefing but I have an Semi established tank, I think it’s been like 4-5 months since I started with Tampa Bay live rock. But I looked at the glass today and saw something hatching? I didn’t see these eggs yesterday or last night but there seems to be little “sprouts” coming out of the brown eggs. Here’s a few pictures:

also FYI, critters I have in tank:
Brittle star
Sea cucumber,
Her it crabs,
2 sea urchin
At least these are the critters I bought.
I know Live Rock comes with a ton of them so, hopefully someone can identify them! Thanks!

Any updates? With real live rock like that it could be anything and I can't really see them well in the pics.
