Acropora spawning
Posted: Wed Sep 10, 2008 10:04 pm
I noticed tonight that my Acropora "millepora" is in the middle of spawning. Normally, I attribute this to a stressor of some sort, but nothing out of the ordinary has occurred for that to happen. I have checked everything--calcium, alkalinity, magnesium, pH, temperature, salinity, etc. and there is no noticeable change, nor did I change anything. All of my powerheads are working, all of the corals seem to be in good shape, with good growth and polyp extension (although I realize the latter isn't really a good indicator). Anyway, I thought it was kinda cool. Basically, all of the polyps swell up, turn a whitish color with a noticeable bulge and "pop" out the eggs come. Unfortunately, I couldn't get any pictures .
