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.
Tropical rainforests produce about 28% of the world's oxygen.
Cells can typically survive without oxygen for only a few minutes before irreversible damage occurs.
The average human brain can survive about 4-6 minutes without oxygen before permanent damage occurs. After 10 minutes without oxygen, irreversible damage and death are likely. Immediate medical intervention is crucial to restore oxygen supply to the brain.
Without life because when plants do photosynthesis, they produce oxygen.

The brain is the most sensitive organ to lack of oxygen, typically lasting only about 4-6 minutes before irreversible damage occurs. However, the skeletal system can survive the longest without oxygen, as bones can remain viable for over an hour without oxygen.
A baby can survive for a few minutes without oxygen before experiencing brain damage or death. It is crucial to act quickly and provide rescue breathing or CPR to restore oxygen supply to the baby as soon as possible.
The brain can only survive a few minutes without oxygen before irreversible damage occurs. Organ failure typically occurs within 5-10 minutes of oxygen deprivation. Permanent damage can happen within 15 minutes or less.
Without life because when plants do photosynthesis, they produce oxygen.
The terms for without oxygen are anaerobic or anoxic.
it depends on the fish.
Anaerobic means "without air (oxygen)". Fermentation allows some cells to make ATP without having oxygen present. Fermentation is not nearly as efficient as aerobic respiration, since it produces a net yield of only 2 ATP per glucose molecule (aerobic respiration produces 36-38 ATP per glucose).
