Recently new to the hobby ordered some live rocks a while ago.
Was wondering what this red growth is in one of them.

Some type of sponge I believe

I don't know what's growing on the rock, but I see you have just joined us here.
Welcome to Reef2Reef!

Kind of looks like colonial tunicates???

Welcome, it is some kind of sponge. Don't let air touch it during water changes or whatever because air will kill it.
