I still can't figure out why everyone gets so beat up about the names. They're all zoas, and I don't get why no one can just leave it at that. If I where to name those though, I'd say gorilla nipple and just generic green ones.
I dont follow the creative names. I think the first is a palythoa. Second a zoanthid. Try squirting some mysis, krill, or brine on the first (red) one and see if it grabs and tries to eat it.
