Palythoa?

Sounds like a moon paly. If it's what I have, mine are white, single polyps living near each other but not connected like a zoa, have longer pointer tentacles like a paly, and have a hint of a blue/green glow. I want to say I ended up with them after a visit to Hobogatos's home.

Palythoa = Big Zoo, dime sized or larger.
