Coral releasing eggs?

My attention was drawn to my tank by my fish. They seemed to be acting as if they were feeding. I was determined to figure it out and after scanning my tank, the only irregularity was "sand" on my open brain coral. Except, something was amiss because I don't have sand this small and the "sand" is sticking together as if there was some kind of mucus membrane holing it together. So, after looking into it, it seems that my open brain has released some eggs. Either that or something is wrong. What do you think?

 

Expelling waste.

 

That seems obvious. Thanks for the input.

 

I always wondered if these lights with programmable cylces would get close enough to nature for the coral to spawn? ? and release eggs and sperm?

 

I've seen it in a video of a large, really well established tank. Never first-hand. I figured it was a really long shot in my tank, but I though it would be interesting to ask. I'm glad to hear it's expelling waste.

 

My Fungi released in my tank, it looked like a volcano erupting a white murky cloud, now i have four babies

 

That is awesome!!!

 

Here's a pic of the baby after it detached from the rock, I have had the momma for five years.
