mollymonticello:
If I may to ask - for the benefit of the people, who asked me about the same, but for pale orange sun coral - when you can, post please:
1. Where larvae settled (LR only or on other surfaces too and what other kinds of surfaces were available for the planula at the same time, but wasn't preferred). For knowing better larvae settlement clues.
2. What caused spawning, in your opinion: daily feedings, particular food, or turning flow off, as
Ameya noticed.
3. What allowed larvae to settle in your tank, not just disappear. I had read assumption, that it's the skimmer removes the floating planula.
May be a separate thread about larvae settlement preferences for a Tubastrea corals will be more easily findable, it's up to you. I could add data for my sun, others may join too. Just an idea.
And for me:
My black sun coral (T. diaphana), starved to the tissue recession, was very slow to open, 5 days or so, comparing to all other suns. Has fastest regeneration so far after mechanical tissue damage.
Did you notice something particular like this about T. micrantha, or about interaction of the two different suns in so close proximity?
I prefer to be prepared just in case, if I will be able to acquire it.
Ajilon, if you don't mind, same comparative information about your corals, OK? Starving for knowledge: hundreds of people are keeping these corals and usually only feeding comes into discussion.
