I have a Euphyllia Parancora hammer coral that looks like it is doing very well in my reef. It opens the hole time the lights are on. And at feed time it sends out its little feelers. It is even growing. But tonight I was blowing of the live rock in my tank with a turkey baster and I blow on the rock under the coral well to my surprise there was allot of little hammer heads that started floating away. It looks like just the heads of the polyps. I gave the hammer a little blow and there was hundreds of these thing floating around the tank. it has been about 20 minuets now and it is starting to open back up. Every thing looks good there is no bleaching the polyps have good color.
Any one have any ideas what this was?
Any one seen this before?

My paradivisa does that all the time. The tips of the tentacles will bud of forming little green balls and drift off. I have yet to see any settle and attach to the rocks. Mine used to produce 3 or 4 vesicles a day, definitely not at the intensity you are witnessing. Perhaps it's something else. I have a E. parancora too but it doesn't do much.

Quote from Eric Borneman's book on Aquarium Corals, "It has been reported on several occasions that sweeper tentacle tips of E. ancora may sometimes stick to substrate and break off, where they can then form new colonies. If this is true, it would be a totally novel and hither to undocumented form of asexual reproduction in the cnidarians and should be carefully verified. Furthurmore, sometimes these tips are readily broken off in currents, having been completely pinched off by the animal prior to release. This does not seem to occur in stressed or weak corals, and it may either be an unreported form of asexual reproduction or a generalised defense mechanism."

Hope it helps.[/b]
