Question

Can the oxygen level in a tank cause a goldfish not to eat?

Answer 1

Possibility, if the fish is not getting enough oxygen they will become very lethargic, and unhealthy, eventually it will suffocate. If you think you need more oxygen, get another air stone, or a more powerful one with a more powerful air pump. Is he gasping? Could be temperature as well. Make sure the temp is low enough for comfort.

Answer 2

yes it can- it can be one of the main factors towards it not eating- if the oxygen levels arent right it wont really do much other than try to get more air

Answer 3

no my goldfish seems fine when i turn on the air pump...its probably bc of the heat
