No problem Nano.
Yep, you are right. You don't have to ever feed your tank if your animals had proper lighting, but that's not what this topic is about. This topic is about feeding your reef.
Now, lets say you never fed your reef tank. That means you have absolutely no fish in your tank that would require a food source to survive. I can say with a lot of certainty that your reef tank would probably be very barren. Your corals might do well, but they would not grow very fast and would probably be dull in color.
But, we know that very very few reefers have a tank without fish. The ones that don't feed their fish are just plain cruel.
So, that means you have a food source. Albeit tiny in comparison to the amount of food that a natural reef recieves.
Seacamp left that part out. Even though these corals can survive on zooxanthellae alone, in the wild they get more food then we'll ever feed our reef tank.
Now, when we talk about food, it's not just the solid nori, mysis, enriched cheesburger food you have to think about. It's the byproducts. Nitrates, ammonia, phosphates... All of these nutrients are absorbed by corals and algae. The cycle thickens; when algae grows, so do algae feeding invertibrates. These are the unseen animals that makup the backbone of our biological filter.
So, you feed your aquarium 1 cube of mysis and three shakes of pellets each day for 1 year to feed your 5 fish. These fish inevitably grow and you're finding them hungry after you just fed them. What do you do? You feed them more.
Not a big deal, but if one of these fish should die and you cut back on the amount of food, then you may also start to see a slight recession in your corals and invert population.
The reason? Even though you have one less fish to add to the pollution, your corals and inverts were relying on that fishes feces to continue there growth. If it's removed from the equasion, animals may begin to die. This is on a small scale mind you.
Finally, back to what this thread is about. If on top of the fish feeding you were feeding your corals and stopped because lets say "a series of unfortunate events" made it a financial burden. You would not feed it and then your entire tank could crash. Remember, I said "could". It would be a domino effect. First, inverts die, nutrients, ammonia, nitrite and nitrate rise. The elevated nutrients is too much for your more delicate corals to handle and they go belly up. The nutrient load has just escalated. The high ammonia has depressed your ph and your fish die suddenly overnight. Now it's an epidemic.
Moderation is the key to this equasion. Corals can be fed, but just remember, if you feed them frequently, then you have to look at the whole picture.
Did I make any more sense this time? I'm sorry if I am confusing, but I have this habit of writing almost exactly like I speak.
Cheers,
