Thanks in adavance

dunno what the first is. are you sure the paler circles aren't actually holes? if they are, I say some kind of sponge.

the second are tunicates, sea squirts. harmless filter feeder.

Both have classic Porocytes (pinacocytes) structure, which would indicate that there sponges and not egg sacks. I know alot of the zoa colonies I have collected have small sponges/ other growths in between the polyps. The purple one is kind of cool looking, consider it a bonus:lol:!

*Edit, sorry the second one is a sea squirt another harmless filter feeder*
