Maybe some day I will try to raise them. They do this about every two weeks. my corals were pretty happy last night though! I have a bright l.e.d. flashlight, and they would follow it all around the tank. So I bounced the light from chalice to chalice, palythoa to palythoa, acan to acan.. It was easy pickings for them

Watching how chalices and acans catch live prey is amazing.. One of my chalices caught about 100 in a slime ball that was completely invisible. Then it slowly "reeled" them in to the mouths. The acans reached their long feeding tentacles out and when a shrimp touched them it almost seemed to get zapped by the acan and very quickly enclosed into the mouth.
