[ATJ]

I target feed my corals with larger polyps, much like in the time lapse sequences. I generally do this with the powerheads off and after lights out (the latter more to stop fish from stealing the food).

For corals with smaller polyps (e.g. Acropora, Pocillopora), I put live Artemia nauplii (newly hatched brine shrimp) directly into the tank with powerheads on but lights out. The corals generally have their tentacles extended at this time and can catch the nauplii as required.

I did try Ladipyg's food "juice" method yesterday in the middle of the day and got no noticeable reaction from the corals. The corals never react when I feed the fish, either.
