Euphyllia divisa spawning???

Hi all,
I picked up a large wall frog/octospawn about a week ago. It settled in well and has looked very happy. Tonight I noticed some “sand” in the water column and figured my pistol shrimp was digging around. Upon closer inspection, all the “sand” particles are round. I turned off the pumps to see if I could determine if they were motile (like some form of zooplankton) or not. No swimming movement, and while the fish weren’t in a frenzy, my clowns were snatching up the ones that made it to their side of the tank. A lot seemed to be concentrated near the wall colony and as I was watching, a short stream of the little balls were released from one section!

So, my question is, what can I do (or should I have done) about this? Are these just eggs that would be fertilized in a natural environment? Should I be on the lookout for baby coral? I was planning to do a water change this week, so I’m not worried about changes in the water quality... it was a pretty small amount anyway and my system is over 100 gallons.

Thoughts?

The pumps are back on now. Should I turn them off for a while to let the eggs or whatever settle? They are all over the place now, but if I have the opportunity in the future, would it be worthwhile siphoning some out and putting in another tank or my fuge?

Nature is so cool! 🙂

p.s. it’s rather difficult to get relevant results when googling “spawning frogspawn”, LOL!

It would be cool to try to save some just to see what happens. Corals go through a planktonic larval stage where I'm sure it's extremely difficult to keep them alive. If you could figure out how to do it, you would definitely be a hero of the marine world, reducing the need to collect wild specimens.

Lol! I think I need to figure out if this particular species is self-pollinating. I only have 1 wall variety and if the eggs need to be fertilized by a “male” then I’m out of luck. I have a lot of branching frogspawn but this is the only wall.

How large is the colony?
Here are a few pics. the third was taken a few minutes ago... lights are out but you can see the skeleton and ruler. The spot I saw release the eggs is the separate "head" at the top left (top right in the first pics). The other two are better shots are better but really don't do it justice... it opens to at least 4x6 inches

In any case, it's better than what I saw yesterday. I was admiring my Symphyllia when it suddenly contracted, almost like a heart beating, and this brown stuff came out. I'm pretty sure it was "using the restroom" to put it nicely. A few fish came over to eat it, but they spit it out quickly, so apparently it tasted like what it was.

LOL! Yeah, my heart has stopped more than once when I see that... I'm so paranoid about brown jelly disease. Big relief when I realize what it really is :)

I had several torch babies pop up on a rock 6 feet away from my main colony so I can definitely say that they do indeed spawn somehow. Those babies have since grown into their own colonies.

Euphyllia glabrescens (torch)is a hermaphroditic brooder, where from what I can find, the other euphyllias are not. Hoping I'm wrong though ;)
