I agee with what kathy said, except.
IM AM A ROOKIE-THESE THOUGHTS ARE JUST MY DEDUCTIVE REASONING AND LOGICAL THINKING-TELL ME IF IM WRONG!!!!
Coral are not like animals in the sense that they do not have brains. they exist soley to exist and expand. If they are hungry they dont think, "gee Im hungry I hope I get food before I die", they are like a computer, no thoughts, just focus on what it wants "food, food, food, food, food, etc......"....that being said,
Corals thriving might not be gd for a tank, to much growth will over grow a tank(which can be gd or bad), and I think, I STRESS, I THINK that very fast growth would change the needs of a tank, as far as whats availabe in the water coloum, and trace elements(I could be bull$h*ting here completely).
Sometimes I want my corals to just survive, not expand much, and I want some corals to thrive and grow alot.
As far as sun polys, I think 1 feeding a week to each head would constitute surviving, and 5 times per week would be thriving.
My dendro's, sun polyps, duncan's get fed almost every day! What they can catch that is, which happens just about every time I feed the tank.
LMK what you think of my statement KathyC...My only point is that corals just surviving isnt a bad thing. It isnt cruel or mean in any way, thats all.
