Any opinions or links to photos? My LFS has one for sale with nice orange tunicates attached. I just need a little more info and google surprisingly has little info beyond how the fishing industry doesn't like them on the hulls of boats.
No.
They are not like the giant clams.
They do not need light. They are great filter feeders.
I dont know that I have ever seen them specifically for sale. They just come on the LR and many dont even know they are there.
TBS does not even sale them individually Live Rock - Tampa Bay Saltwater Aquacultured Live Rock - Price List
