as long as you want
That depends on the size of the fish and the size of the container. It is the build up of ammonia and depletion of oxygen that kills fish under these conditions. It is possible to keep some small fish alive in a small container for a while but use your common sense and observe the fish. If you see them stressing, change some water.
they cant do to lack of oxygen beiing used up.
No.
No, unless the container he/she is in is small
the gas that released by fish is a carbon that the fish can live at the water without a air. and the fish can not live if without small amount of air. and process by breathing with amount of air that all the animals and humans can breath.
That would rather depend upon the size of the fish and the size of the bottle. In general, fish cannot survive in a closed container that doesn't allow the fish to get oxygen. The surface of the water is where oxygen diffuses in and carbon dioxide diffuses out. All other factors being equal, fewer fish can survive in a tall thin container than a short squat one. If you are willing to provide appropriate lighting, it is possible to balance the fish's oxygen and food needs with oxygen and food provided by green plants. If you strike the right balance, you can seal the container and the fish will survive. This is popularly called an "Ecosphere". See http://en.wikipedia.org/wiki/Ecosphere_(science).
Gills allow the fish to extract oxygen from the water. Without oxygen, the fish would die. So the answer is TRUE.
you get a net to take out the fish and put it in a container while you're cleaning the bowl and put the fish back in when your done :) hope I helped :)
Yes, mine is fine!
Water has oxygen dissolved in it. It gets this oxygen from plants, agitation, air stones, air to surface transfer, etc.. Fish require oxygen to live. If there was actually no oxygen in the water, the fish would suffocate in minutes. Otherwise it would depend on the amount of water, the number of fish, and many other factors.
i recommend that you have a filtration system in the bowl as during the day plants will give off oxygen while it photosynthasises but at night it gives off gasses and the fish needs to the oxygen to breath. the plant will not be enough for the fish and if you do not have the room for a basic filtration system then the bowl is to small for the fish
There are some fish that have evolved over the millenia to survive for a while without water because they have developed methods of either using or conserving oxygen. The vast majority of fish however can not get oxygen from air because they have gills rather than lungs and so they can not breath without water flowing over their gills.
