Help IDing these please

[TheFunnyFarm]

I found the following and for the life of me cannot find anything close while searching:

There are two of these on the back pane (out of normal view)


This is, for lack of a better term, encrusted on the backside of my live rock. I did a poke test and there wasn’t a reaction. This is as close I could get without loosing resolution


I’m getting ready to transfer this tank into a new build so I’m a bit nervous.

Thanks for your help!

Colonial tunicates - generally harmless filter feeders, but a few species are extremely invasive and can overgrow some corals and macroalgae. If you think yours are invasive but you want to keep them anyway, I'd sequester them on an island where you can easily trim them back as needed.

Eggs may or may not make it. Often, they become caviar for tankmates and require cooler temps for successful hatch
