Is it OK to put a glass lid on the fish tank?
In the case of sufficient oxygen supply in the tank, a glass cover over the tank can effectively prevent the fish from jumping out of the tank.
Many ornamental fish have the ability to jump, which is the ability to escape predators during evolution. In a small bowl, because they do not fit or frightened, so often jumped up, sometimes jump out of the tank to the outside, a fall from a height will fall, when no one is around, the fish will die because of water shortage, hypoxia on the outside.
A glass cover over a fish tank prevents this from happening and helps conserve. However, because the aquarium is covered with glass cover, blocking the air and water exchanges, will reduce the amount of dissolved oxygen in the water, there must be oxygen equipment will not make fish hypoxia.
