The Advantages of Keeping natural Tank

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

I like the way you write. I see your point about disease resistance. I often wonder if bottle feeding is effecting the disease resistance in children.
Would bacteria on dirt survive in a saltwater environment? If not, getting immunity to it might not be the best idea unless it works like exercise. Getting mud from the ocean would seem to be more reasonable, although would that bacteria live in warmer waters?
Where do you get live clams? Do you have to go to the ocean and buy them there? Do you chop them up before freezing?

Mark, here is a link to an article I posted on immunity. A discussion on Immunity

Bacteria from the sea will have no trouble living in cold or warm water. The tide pool where I collect goes from about 35 degrees in the winter to close to 90 in the summer as it gets very shallow at low tide but 8' deep at high tide. Many (but not all ) bacteria will also live in salt or fresh water. That same tide pool goes from full salt to almost full fresh water with each tide because it is a salt marsh, but it is fed from a lake. If I look close and maybe squint, the bacteria are smiling no matter what. I feed blackworms every day for the bacteria in their gut, blackworms are freshwater creatures and I know they boost my fishes immune system from feeding them for fifty years so I assume their bacteria live in the stomach of salt water fish.
You are in New Jersey so I am sure you can buy live clams at any fish market or supermarket.

Bottle feeding is supposed to not be the right way to raise children. New research seems to point to those babies having a much higher rate of being allergic to things as opposed to breast fed infants. WE were not designed to drink cow milk unless we are cows.
I think bacteria from dirt would survive in salt water and even if it didn't, the fishes immune system would make antibodies from the dead bacteria just the same. The more the fishes immune system recognizes as a threat, the better off the fish is.
Bacteria from the sea is best.
I buy chowder clams live, then partially open them and stick something thin like my wallet in their shell so they can't close. (they hate that) Then I freeze them, (they hate that more) open them, and shave off paper thin slices. Bigger slices for bigger fish.

I don't really write "good". I scribble this on my computer screen in red crayon, then an unemployed Supermodel comes over and types what I wrote in crayon under my scribbling, she erases each crayon letter as she types. :rolleyes:

I see your point Paul. I am nervous to collect from the bay by in NJ right down the street from me. I used to add snails and hermits I found at the beach, ocean not bay, to my first tank but felt they caused issues but maybe not. Where I live all the mom n pop LFS closed so I cannot get live tubifex, black worms etc.
This is why people make there own fish food IMO.

P.S. Also would feed my nem and eel live clams.

I take whatever I find in the bays in the Sound if I think my fish will eat it. But I keep a natural, immune tank so it doesn't matter what I add from where ever. :D
 
I didn't want to see this post die without some discussion in it.

I was expecting a picture of the supermodel as well.

How do you feed the worms, just drop them on the tank bottom or spread them out at the water surface? Or do you use some sort of cup with holes in it for them to crawl out of? Do the live very long in the salt water?

From the articles, it suggested the slime coat is very important and results in response to bacteria or pathogens. I though I read that bacteria can be obtained from the water. Does the bacteria get into the slime coat and help more by competing for food to keep the bad bacteria or pathogens in check?
It appears that from what was written, that immunity only comes from exposure, and exposure should be limited to fish exposed to bacteria.

I would also think that if my fish aren't spawning, it may be more due to the foods and bacteria they are missing. (Or maybe just a single fish or 2 males)

Mark (or is it Shelly?) I would never put any type of food in my tank without "shooting" it in with a baster thing that I make. The worms die in about 8 seconds so I don't want them on my gravel although the fish eat them dead. They normally get eaten as soon as they hit the water as this video shows. Here my copperband was young, she is much larger now and needs clams in her diet. I also feed white worms which live for hours in salt water and are just as nutritious (I think)
The bacteria I add to my water in the form of mud is for the water quality and I don't know if it does anything for fish health. The live foods I give to my fish is the reason my fish are immune and spawning. The bacteria and parasites in the food allows their immune system to function normally and keep the fish healthy (as the link I added to an above post states)
All fish exude slime no matter what condition they are in and the slime is water soluble so it washes off and needs to be replaces continuously. That takes a lot of calories and energy to do that. But if the fish is not immune from the bacteria and parasites, that slime is just slime and won't have anti parasitic and anti bacteria properties in it so if that fish encounters parasites, they will hold on and maybe destroy the fish.
If your fish are "Paired" and they are a type of fish that will spawn in a tank and they are not spawning, they are not healthy. Healthy female fish make eggs all the time no matter what. If there is no male they may go on one of those dating sites like "Too Many Fish . com.)
Every fish in this video, with the exception of the copperband, is spawning.

 
I cant play the video for some reason. I have followed many of your posts about this on many forums. I like the way you explain it and I may try it on my new setup. your success is as far as I can tell unparalleled. Not too many folks out there with a 46+ year old tank that the fish die from old age.

Thank you EricP. If you can't see the Video. Just stare at that picture and move your monitor back and forth. :D
If you try my system. many people will laugh at you. I can hear them laughing now as it can't possibly work. :rolleyes:
 
They can't argue (or match) your results. I used to keep a freshwater tank in a similar fashion. Live food and plants and stuff I got from small ponds in north jersey. The best was one batch of plants had dragon fly eggs on it that I didnt notice until they hatched and I had a room (and tank) full of dragon flys. I suppose the fish did eat alot of the larvae but probably 20 grew up. maybe 10 escaped into my bedroom.
