Anemones are one of those things. I love my two giganteas but man, they are getting huge and taking way too much space from my other love in the hobby(SPS).
How about an anemone dominated tank? I'm sure Bob will be happy.
Flower pot corals are commonly refer to goniopora. Not to mistake with alevepora, gonipora has 24 "pedals" tentacles while alevepora has only 12. They are very commonly mistaken.
A bubble tip will sting and most likely kill a rock nem.
One of my rock nems moved away from a ricordia because it was being stung.
