Spawning events

[Kensington Reefer]

Over the years I have had the good fortune to witness various species spawn.
This evening, around 5:00, I saw one of my urchins releasing gametes into the water column.
I was wondering if anyone else has seen any at this time?
Is the cause related to the lunar cycle or perhaps by water chemistry?

My buddy’s urchin did that almost every time he did a water change. It was a huge tank with fist sized urchin though.

My former longed spine urchins released white stuff at 1615 in October. They made the water column cloudy. These ones munched on my corals.
