If you're looking for scientific names, good luck. Even the vendors rarely have these. If you're looking for common names... again, good luck. The exact same polyp may have a dozen names depending on who sells it. All I can tell you for sure is that you had zooanthids. And while some may recognize color varieties, it's next to impossible for anyone to identify them for sure. Two species may have nearly identical color morphs.
All that aside, they're gorgeous and I'm jealous.
