Duncan coral spawning…?

[Edgecrusher28]

*This was a Trumpet coral, not a Duncan; I’m stupid*

I was randomly checking in on the tank before calling it a night and noticed what I thought was my Trumpet coral spawning. It was releasing what looked like smoke, just like I have seen from snails dozens of times, but this time it was out of the mouth of a duncan. Any specific triggers for this? From what Ive gathered this only happens maybe a few times a year. First it was a chalice eating a Lepto frag and now this, things have been interesting as of late.

I know for a lot of corals, lighting (both daytime and nighttime lighting) and temperature seem to be the main triggers. That said, there are a number of different triggers that may play a role (I'm not sure for trumpet corals specifically which ones would matter):

"The triggers for spawning involve a variety of environmental signals, including daylight hours, water temperature4,5, wind speed6, moonlight7, tides8,9 and hours after sunset10, with cues operating on increasingly fine temporal scales."*

If you know the triggers and can control them well enough, you may be able to get the corals spawning out of season.

Split spawning realigns coral reproduction with optimal environmental windows - Nature Communications

Corals usually undergo single mass spawning events, however, occasionally they split reproductive effort across two months. Here, Foster et al. use 10 years of data to determine the drivers and timing of split spawning, showing that these events realign spawning with optimal environmental...
