Thanks for the replies guys! I am familiar with aiptasia's as I have dealt with them before with the help of peppermint shrimp and a copper banded butterfly. I am almost 100% certain that these are not aiptasia's as they do not have a translucent stem, as most aiptasia's often do. I do think these are some form of zoo's.
Thanks for the insight on the zoo's, Fluff! I didn't like these guys at first, but they soon started to "grow" on me. I just wanted to get an idea of what they were!
