Do goldfish like the light on or off?

Do goldfish like LED light?

Should I turn my goldfish light off at night?

Aquarium fish do not need light and it is best that you turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.

Why is goldfish staying at top of tank?

A fish may linger near the surface because he’s trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.
