Secondly, pour in a fresh amount to fill up the fish bowl again. That is the simplest way of how to get oxygen in a fish tank without a pump.

2. Ice cubes can help

Ice cubes can come in very handy if the low oxygen levels in the tank happened because of an increase in temperature. If the water is too warm, it contains a little amount of oxygen, which might not be enough for the fish.

If this is the case, you should toss a fistful of ice cubes in the fish bowl. This is going to help cool the water and increase the oxygen level.

3. Reduce the number of fish in the bowl

Thus, to make it easy for your fish, just change the water daily. Just add a pinch of aquarium salt in the water before you put your fish back in. If you forget to change the water for a day or two, the salt will prevent the growth of bacteria.
