How do I know if my fish tank has too much oxygen?
The signs of too much oxygen in a fish tank are bubbles escaping the surface and increased dissolved oxygen levels. Fish will also show abnormal swimming behavior, open mouth breathing, excessive appetite, or lethargy. If left unchecked for too long, it can be fatal to the fishes’ health.
How do you cry fish?
Fish can’t cry because they lack the part of the brain which makes us humans able to produce tears. The part of the brain that produces tears in mammals is called the cerebral cortex. Fish won’t even be able to engage in something similar to crying.

Why is my fish gasping underwater?
When fish gasp at the surface, it generally follows that they are short of oxygen. Often this is due to other pollutants such as ammonia or nitrite interfering with healthy gill function in the same way that we might fight for breath in a smoky atmosphere or in the presence of noxious fumes.
Can a fish drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen.
