Im not sure what this is, spawning or feeding? My gut says feeding because this happened when I purchased some new coral food from my lfs, "phyto feast live", and fed it to my tank for the first time. I have only seen this happen once, so it still has me confused. Anyways, it makes for a great picture.

Feeding... Those are quite the tentacles on that thing.
