Agreed - colonial tunicates:

Haha, yeah sorry - that's part of why I threw in the TLDR at the bottom there. Here are some photos of colonial tunicates with similar body structure (and some with - from what I can tell - similar coloration) to help decide if it is a colonial tunicate:

Ascideacea

That’s a colonial tunicate species - harmless filter feeders, but some species can be pretty invasive, so I’d try to keep it isolated.
