Can some one indentify some things for me?

#1 looks like a Pipe Organ Coral - Tubipora musica

#2 is a Neomeris algae

#3 resembles a Majano Anemone.

#2 is definitely not bad. It's not invasive and doesn't harm other organisms.

#3 is up for debate. I'll say I would remove it as Majano can multiply rapidly when food is available and they will harm corals that invade their space.
