Coral spawning?

[Son Of Skyline]

I've been seeing footage of coral spawning in nature recenty on the good old Discovery Channel. Has there ever been a documented case of this happening with corals in captivity? It seems very interesting.

I know that Chris (pocilipora) had some pictures of it happening in his tank.

I think I remember reading that generally only large, mature colonies will spawn. I mean large as in bigger then what most of us have in our tanks. I have also heard of corals spawning as a stressed responce to a sudden change in conditions.

Do a search on RC and you should find lots of info.

Hi,

I had two spawnings happen in my old 20 gallon...not good in such a small tank. That week was water change galore....

Sweet! I guess it's not as uncommon as I thought. Is this spawning ever actually successful?

Look at Shao's cleaning magnet. Grown from a poccilipora bud/planulae.




I haven' heard of acropora spawning succesfully in captivity, but I'm sure its happened.

The pocillopora piece that Shao has is from polyp bail out. Its not uncomon in this type of coral. It is not a form of spawning.
But yes I did have a Large acro that has spawned several times. Its always happened at night, but nothing ever grew from it. I could always tell in the morning before I would go to work that a spawn happened because you can smell it. Extreme fishy smell, and the skimmer would not be working.

I'm with Chris, I was just gonna say .... I'll have to take your guy's word for it.
