kenyas, xenias, all grow very fast and are low maintenence. Zoanthids come in every color formation available and are easy too. Mushrooms, and some LPS are pretty easy too.
Anemones are mobile creatures and can sting other corals, but I would say that shrooms are the safest with them. And anemones move slowly so if you're around and worried about them you can just keep an eye on the anemone.
wow Thomas, where did all of the anemones go?!? lol It looks great
I woudl be willing to buy or trade you for one of them if you still have them. (In case your looking for places for them)
