Thanks BayouCorals!
I use the blues (LED) for "moon lights" at night and no obvious glowing little bodies thus far, but now that you say that, I'll look closer tonight without my flashlight. The one baby I still see, is still a quarter inch in size (I said half inch before, and I'm quite sure I had brain fart because it's definitely not a half inch). I've not been home to feed it while the lights are on. It's hidden in a dark cave.
My rocks are pukani and premium dry rock (looks like dry acropora) so LOADS of hiding places and not much coralline yet (new system). I suspect I may need to wait and watch until they start coloring up.
