ID some stuff on my live rock

[alex77619]

I have found these little thing on my live rock and want to know what are these stuff and are they harmful

The white stuff looks like sponge maybe which if it is, is harmless.

The orange could be majano or aptaisia which is invasive. Is it hard or soft?

The white dots look like something I have in my tank that someone else suggested nerite snail eggs. Do you have nerites?

The orange thing looks soft and will retract back to a orange spot. I do have 2 peppermint shrimp in my display so I thought I won’t have aiptasia. And my tank is 4and a half month old only but so far only one of this orange stuff is spotted.

The orange thing looks like mojano. Do Peppermint Shrimp eat them?

Orange looks like a little sun coral...I'd let it live.

Currently no sign of peppermint shrimp eating them. But it seems to not have a body that will attach out like an anemone and it’s now at the bottom of my tank which it also doesn’t seem to starch for light and pull long.

I do have a big sun coral that I feed everyday in my tank. So it reproduces and landed there? Kinda amazing if it really is a sun coral because I never feed that area for months already.

That' what it looks like could have been polyp bailout...idk but I'd watch it...
