What are these?

[Seascapes]

I noticed the growing on the back. Picture one looks like snails but the other picture that looks like flowers don't have a clu. Please help. Thanks

They look like colonial tunicates to me.

OP, these are very cool looking! If you're near Houston and feel like sharing, once @ISpeakForTheSeas gives the thumbs up/ID, I'd love to try tunicates in my tank! :)

And the "snails" are limpets :)

They’re definitely pretty - they look like Golden Star Tunicates, Botryllus schlosseri, to me (the “normal” color for these is brown outside, tan inside, so OP, yours are kind of fun being flipped from the norm; that said, they come in a wide range of colors, including deep reds, oranges, and yellows in nature).

A beautiful species, and one that you can find for sale if you know where to look - but, they can be pretty invasive (see the link below - they have the same color tunicates even), so you may need to be prepared to trim them back regularly if you don’t want too many of them in your tank. Other than their rapid spreading, though, they’re harmless, pretty filter feeders.

Tunicates

So I have these tunicates in both of my 150s and I’m pretty sure I’ve narrowed down the source, but I’m wondering if anyone else has experience with this kind of tunicate. Will they eventually die off? It doesn’t seem like they sting corals to me, but has anyone experienced that? They are...
