After hours scouring the net, my best guess is that they are tulip anemones. I'll watch them and see how fast they spread. They really are very pretty so I'm not sure I want to nuke them yet.
Yep those are majanos, ya they are actually very pretty pretty but really bad, nuke them right away. Kalk paste works great.
If you dont they will spread like wildfire and kill and eat all your corals and anything else they can get a hold of.
