Thanks all.....I do target feed my acans (I target feed all of my LPS when I'm not being lazy).....not because they need it to survive, but because they grow faster and require less symbiotic algae living inside of them and thus I believe that enables better coloration of the coral (that is the premise for the zeo method and all of the hybrids). That said, I have no data to back this up except for experience watching the corals response to feeding.
cheers,
Darren
