Zoos are a pretty hardy soft coral. They like moderate flow and low-med light. They don't require any special feeding, and can spread well in the right situation.
For some reason Zoos and Ricordia don't fair well in my tank. They stay alive for years, but don't proliferate like I hear so much from other people. I think I might just have too much light for them, not sure. SPS
do great! Other types of mushrooms too, just not Ricordia, which really blows, because they are pretty much my favorite shroom.
Zoos and mushrooms would be a great place to start for you!
