Hi managed to get a video of my corals spawning. It's a crappy iPhone video but will give you an idea of the mess it made of the tank within 5 mins. I've just been told that here in Aussie, corals will spawn once a year 5-7 days after a full moon in March/April. Last full moon here was the 4th March.Apparently reef tanks will keep in time with the reefs here. This is such a fascinating hobby.
