The advantages of keeping a natural Reef
We all know that there are many ways to run a tank but I would like to start a thread about keeping a natural reef. The ocean is natural and the fish there are all very healthy and never have to worry about getting sick, getting enough food, getting enough sunlight, exercise etc. They do however have to worry about getting eaten by something larger or getting caught in a net, suffocating on the deck of a ship then being stuffed into a small can labeled "Dolphin Safe".
None of the tanks we keep are natural by any stretch of the imagination but I feel we should strive to get as close to naturel as we can.
There is a reason for this thinking. Fish in a natural, unstressed state are just healthier. They are healthier because they eat better and by that I don't mean the foods they eat have more nutrition, although they could have. I mean they eat healthier because the foods they eat have the living bacteria in them that help keep fish immune from disease.
Fish are different from most of us and some of us smell better than fish. Fish in the sea eat mostly fish and crustaceans and many of us also feed that type of food, but fish in the sea eat whole fish and crustaceans, bones, guts, eyes and all. It is difficult for us to get very tiny whole fish for food and I discussed this point with fish food manufacturers a few times. I can buy very tiny whole maceral babies in an Asian market but they are always freeze dried with the consistency of wood. Fish won't eat wood and neither would I.
My last few weeks in Viet Nam we were issued what they call LURPS. It's basically freeze dried stew but if you tried to eat it without adding boiling water, it would be like eating Styrofoam with powdered Styrofoam on top of it. Our problem was that we hardly had water, much less boiling water. If you just added water the same temperature as our tanks, it would just float, and you still couldn't eat it. That’s the same problem with trying to feed our fish freeze dried food.
The ingredient in foods that will keep the fish immune is the bacteria and parasites in its gut and a wild fish eats that at every meal. A fishes gut, or intestine and stomach is filled with bacteria just as ours is. We and the fish need that bacteria because it is that bacteria that keep us healthy. That is the reason that when we take antibiotics we get the "runs" and feel lousy. The antibiotics kill our stomach bacteria and we can’t live without it. I don't really know how fish feel but I do know they are supposed to have a gut filled with live bacteria and parasites as all the fish in the sea do.
That is the reason fish in many tanks are so delicate and the reason for all the disease threads. Fish are actually very robust and rarely, if ever get sick on the proper diet. A healthy fish in a natural tank will eat right away and not hide for days at a time, unless it is a type of fish that is supposed to do that. All healthy fish will also try to spawn. Of course if you have an algae blenny it won’t try to mate with a whale shark.
So many people have trouble with feeding fish such as mandarins, copperbands, moorish Idols etc. That is because IMO, it is not a natural tank.
When we get the fish from a store, that fish may have been collected a month ago. In that time it was not eating the food it is supposed to eat along with the bacteria and parasites it is used to eating. It’s like us on antibiotics and its stomach and intestines are not working properly because a fish gets its immunity from its kidney and the kidney knows what types of immunity it should churn out by the types of bacteria and parasites in its stomach.
If we get a new fish and put it in a tank with copper or antibiotics, that fish is off to a bad start. I myself used to do that. Treat new fish just to make sure they were “healthy”. I learned the hard way that that is not the way to go. Naturally if we get a fish in the process of having last rites, or if an angelfish is giving it mouth to mouth resuscitation, we have to treat it, but we should rarely get a fish like that.
Healthy fish in natural tanks spawn continuously because that’s what fish do.
The Mother fish imparts her immunity to her fry so it can survive its first few days outside the egg because a fish fry has a thin coat of slime which is the fishes only defense against pathogens. If that slime doesn’t have any immunity in it from its Mother, it cannot survive because it will be attached by every pathogen in the sea, or a tank. If it’s Mother doesn’t have immunity, neither will its babies because where would it come from? The baby fish hasn’t yet been exposed to anything so it could not get any immunity and it would not survive. As that baby fish starts eating, it consumes bacteria and parasite laden foods which it should be immune to, but only if it got that immunity from an immune Mother.
If you keep a sterile tank with no input of natural bacteria or parasites, that fish will always be at risk of infection from bacteria, viruses and parasites so everything in contact with it needs to be quarantined. But even if you quarantine everything that is in contact with that fish, you can’t keep all disease bacteria away from it, especially if you buy coral or rock because those things, even if quarantined for years can harbor disease pathogens in the form of viruses and bacteria that quarantining will have no effect on. Quarantining can remove parasites, but nothing else.
You can’t turn a sterile, quarantined tank into a natural tank very easily because those fish have no natural immunity to anything because they are not exposed to anything so it would be a slow and possibly scary process. The fish would need to become infected, and then cured by un natural means until the fish builds up immunity or unfortunately, dies.
It is much easier to set up a natural tank in the beginning but of course that can also be scary, especially if you are new at this. If I were to set up another tank tomorrow I would do it almost exactly like I set up my present tank. Reverse Undergravel filter and all, but I doubt the UG filter has much bearing on the health of the fish.
I am lucky that I can get some natural water and mud from the sea, but I also add regular dirt from outside my house. Dirt that doesn’t have pesticides, fertilizer, weed killers or battery acid from a 1957 Oldsmobile Cutlass. I add a little soil, not for the soil, but for the bacteria. If I collect earthworms for food, I leave the dirt on. It’s the same dirt that is inside the earthworms. Eating a little dirt won’t hurt us and it won’t hurt your fish.
I would also feed something with live bacteria in it at every meal. I use white worms, blackworms, earthworms, or clams that I buy live and freeze myself. Clams that you freeze yourself would still have the same bacteria in it as when the clam was alive because our home freezer is not that cold. Processed fish food you buy is questionable as to the presence of bacteria because it needs to be somewhat free of bacteria so it can last and be sold. It may also be irradiated.
(If I could only use one food, it would be clams)
Our fish should only die of old age and fish on the proper diet in a natural tank do.
This is all just my opinion of course and I would like to hear your ideas on keeping fish healthy

Today I am taking a bunch of cousins on my boat to the Statue of Liberty. I may bring my copperband along and let him swim around Lady Liberty to get some Patriotism . I think she came from South Africa but got her citizenship when she was a teenager.
