How long can tropical fish live without air?

Answer 1

If you have a balanced aquarium the fish will live perfectly normally without a filter but it is hard to do. To achieve this, you would need to have the correct amount of well established plants growing, and the right amount of fish so that the plants and fish support each other. The lighting would also need to be spot on. Too much and algae will take over and too little the plants die. Then you would probably only need to top up evaporation losses and change some water when the GH starts to climb and the nitrate levels get a bit high. If you have neither a balanced aquarium nor a cycled filter, the other way to keep the fish alive is to do very regular water changes. The last method is not recommended because of the variation of the water quality. Each time the quality goes down the fish will suffer damage and that will shorten their lives and/or make them sick.

Answer 2

Tropical fish can typically survive without air for a few hours, depending on factors such as water temperature and oxygen levels in the water. It is important to ensure that proper aeration and water quality are maintained to prevent stress or harm to the fish.

Answer 3
