Yes, I have. But have you ever heard that those bacteria don't live in water, they live only on surfaces?
Yes, they live on surface, but they are in the water, full of nutrients for them. Their nutrients are the waste from the fish.
What can I say... Hmm... If there is too much oxygen, oxygen is toxic. Air, you breathe, contains only about 21% of oxygen and 78% nitrogen, 1% other gas like argon... If you want to know more, try to use google by using e.g. "oxygen +toxic +fish" etc...
Hmm. Have you ever seen fish that lay eggs. They fan their eggs. Do you know why? Water movement oxygenates the water. WHen you use airbubbles in a tank, the airbubble is not injecting O2 in the water. The actually movement as the bubble rises and pops DOES oxygenate the water. Yes, fish cannot breath oxygen, they will die. But their body is built to take oxygen from the water. When fish swim around, they consume oxygen yet their actually movements also oxygenates the water. BTW, I did a search and could not find a SINGLE THING. All I can see are low DO (dissolved oxygen) issues. I found the following at
TheKrib.com
Fish need oxygen, and some fish are more tolerant of low-oxygen water than others. Water with insufficient oxygen stresses fish. Note that as the water temperature goes up, the amount of dissolved oxygen in water decreases.
Please provide a link to where you get your information. Here is another source, which contains information from
PetEducation.com regarding what happens with O2 when power goes out
One of the first things that happens when your power goes out is that the oxygen level in your tank begins to decrease. There are several things that speed the depletion of oxygen including:
* A heavy fish load
* Increasing temperature
* A heavy plant load
* Feeding the fish
* An increase in fish activity
Fish require oxygen, so if the tank is heavily stocked, moving some of the fish to a lightly stocked tank may help. If you have a heavily stocked tank and live in an area where power outages are common, a generator may be a wise purchase.
If that were so, then I guess you would just throw your fish in your tank as soon as you take it home from the store.
No, you shouldn't and it's based on harmful bacteria in water New fishes may become sick, because they do not have resistance to these new bacteria.
But earlier you said bacteria LIVE ON SURFACES? You are NOW contradicting yourself. BTW, when you buy fish from the store. Take a look where they get the water from to put in the bag with the fish. I guess, with your theory, just ask them to put the fish in tap water so your fish at home does not get any diseases.
Books are very good sources of information
Could you please name of few books. I LOVE to do research. I like to be very knoweledgeable with aquarium fish. I consider this as a serious hobby. (Yes I do have a life and a girlfriend). I just don't like it when people give incorrect information.
Don't ever add oxygen to cories, labyrinth fishes etc. that can breathe air above surface.
Uhmmm. I'm not sure if you know this, but fish cannot take in O2 like we do, they do not have lungs, but gills. Their gills allow them to take in O2 from the water. Even if you took a fish out of water and kept it's skin moist, it would die, since it will not be able to breath. Basically, it's like them drowning with air. Just like us, if you stuck your head underwater that is very well oxygenated, we would drown, because our lungs are not designed to take O2 from the water. (I learnded dat frum mye skoolin)
BTW, I'm a moderator at another freshwater forum and I'm sure they can vouch for me there that I do not give any wrong information. I also used to work at an LFS at a time where I was "in between" jobs after a layoff. As I mentioned, I LOVE to do research and will be glad to read any TRUE information you or anyone will provide. I also have access to several aquarium books at the LFS I used to work at, also a library by my house, and a local bookstore so I am WILLING to look up the information provided to me so I can verify.
Sairie, I apoligize for this. If you have any questions, another good resource would be a privately own LFS, not those major LPS, like Petsmart, Petco, etc. Those are mostly highschool or college students who probably have never owned any fish.
