Scott, you said to burn them. Wouldn't that hurt the coral? What's the best way to get rid of it if it is aiptasia?
Yes, it's a species of Aiptasia although I'm not sure which one. Some of the larger species are safer than the tiny ones that take over your aquarium, so it may be fine as long as it doesn't spread or sting anything.
Do you dip coral RX prior to the display tank?
