how long do you think 25 1-2 inch fish can last in a tank with no water agitation? need a quick reply if possible
how long with no water agitation

depends on the volume of water their in.... think about it.. if u put them in a glass of water do u think they will live very long?
all of that aside and given that no ammonia spikes occur...
36 hours maybe 72 max.
temperature would start to play a big role. cooler water retains oxygen better and slows the metabolic rate down, which would result in less waste being produced.
i would be more worried about the beneficial bacteria dying off... if indeed we are talking about a tank set up.
as long as your breaking the surface area of the water there is gaseous exchange.. no you dont need to have bubbles in the tank.. just slowly stirring it like you said does work.. as long as your bringing the water from the bottom of your tank to the top it will be oxygenated.. BUT.. as a fix when you cant do anything else.. Id get a BATTERY operated air pump.. was just thinking this would help if the problem was power outage
thats BS no scientist ever did any experiment to prove that they dont work the myth is that the increased oxygen is a result of direct absorbtion from the bubbles when it isn't. it's becuase of the buubles breaking at the surface create surface agitation and accomplishes the same thing as stirring the water except you wont have to sit there for 3 days straight stirring the waternes999;3745753; said:
If it's a larger tank, they may be okay. If it's small, it's probably to late. Watch the fish for gasping at the surface, that is a sure sign that there isn't enough o2 in the water. You can stir it, but you are much better of aerating the water.
Bubbles in a tank do work well, and they cause that slow turnover that mentioned earlier. That is what aerates the water, not the direct absorption of o2 from the bubbles.
A couple of options. 1. Lower the tank temperature some, if possible. 2. leave a small bucket by the tank, and each time you walk by, fill the bucket and then pour it back into the tank. Try to do this every half hour or so. 3. Do the simpler thing and get some battery operated air pumps. Walmart sometimes has them, look in the fishing section for bait savers.
If these are anabantoids, don't worry about it, they'll be fine.

I agree with many of the posters on this subject; it depends on the type of fish. This kind of situation should be avoided at all costs, of course. But in the case of a power failure or shipping in large containers, a battery-powered pump is ideal. Pointing the pump slightly upward at an angle toward the surface should agitate the surface to help with gas exchange. Just out of curiosity, what kind of fish are you asking about? For example: There's a huge difference between having a couple dozen+ 1-2" female bettas in a stagnant water container than 2 dozen+ 1-2" baby oscars in a stagnant body of water. Certain species of fish- such as bettas and gouramis- have a labyrinth organ that allows them to breath some surface air and use it in addition to water they breathe through their gills. Lungfish, needless to say, are masters of air breathing as far as fish go. Oscars and other predarory cichlids aren't good at extracting air from the surface, and they also produce more ammonia for their body size than another fish that has less girth. Knowing about how "dirty" a certain kind of fish is will dictate how long it takes before the water they are in becomes too saturated in carbon dioxide and ammonia.
