Interesting... Would gestation last over 8 - 9 months? (Probably more since the corals were sitting with the suppliers for at least another 1 - 2 months before they arrived here)Great! You likely have brooder species (different from pocillopora in that they take in sperm, but mass spawn later, rather than releasing larvae all the time . Given the time frame, you corals likely came in fertilized and you did a great job of keeping them happy enough to cook all the way through. This has been happening, at least that I am aware of, since the early 2000's and we are seeing it more as people know what to look for. Great job!
I can't really say that I have kept them happy... the torches went through several stress events from infection, to Ca spike due to a runaway DOS, etc.
What's interesting is that I didn't see any egg like or larvae like elements in the release from the holygrail. the excretion was more like a sperm release. And then last night, I saw my green torch release a clump of what looks like eggs surrounded in mucous.
I read an article of the UCA team creating 2 instances of successful aussie gold tank-spawns. Article mentioned a Nov - Dec spawning event. So I was surprised to see that spawning in my tank ahead fo schedule, assuming that my indo torches follows a similar rhythm given geographic proximity.
Guess time will tell. Let's see if a second spawning might take place.
