I think I’ll never stop finding something new

Anyone able to ID these? First is a fleshy like lump with a red mouth like feature attached to my live rock, idk if it’s always been there but as some of my sea squirts fell off from pesky crabs is when I’ve noticed it. Bellow the bubble tip nem surrounded by the red.

I’m unsure about this one, but it seems to be growing in size and forming sharper edged features. That or I’m just imagining this.

To the left of the white sponge.

These both seem to be tunicates (sea squirts) - the first one seems to be solitary, and I would guess the second is as well, but I can't tell for sure from the pics.

Solitary tunicates are harmless filter-feeders; colonial tunicates can sometimes be invasive to the point of being harmful, though, so I typically recommending containing those on a rock separate from the rest of the rockwork where you can easily control the spread.
