Why does my fish yawn?

The most convincing theory currently is that yawning serves to cool down the mammalian brain, which fatigues as it warms up. However, such a brain cooling mechanism is unlikely to benefit fish since, as ectotherms – cold blooded animals, their body temperature is controlled by that of their environment anyway.

You can tell that fish sleep by turning on the aquarium light or diving at night. The fish will be generally unresponsive to stimuli and can be easily caught or handled. I have used this to advantage when I have needed to remove fish from an aquarium with a lot of rocks.

Fish do not have eyelids so they sleep with their eyes open. They often retreat to shelter, such as a plant thicket or near a piece of sunken wood. Many fish also will change color, the colors possibly becoming muted or darker. In the aquarium some just settle near the bottom of the aquarium.
