Do Fish Get Tired at Night?

Question

Whenever I come downstairs at around 12AM, my fish always seem less active. During the day they swim around, but at night they go to the very bottom and swim slowly a few millimetersoff the gravel. Is this normal?

Answer 1

Well fish do have a night and day cycle just like us.

so at night they do rest and become lest active.

Answer 2

Of course it is! You may notice their colours are somewhat paler as well.  They're just resting/sleeping.  No need to worry, fish need to sleep as well.  So it's important not to keep the tank light on 24 hours a day.  Turn it on when you wake up and turn it off around the time the sun sets.

Answer 3

yes. if  you keep the lights on at the late, late pm they will get stressed out and you may notice a change in color depending on type of fish. They are living and need rest time also. Same goes with live plants, they need a break from the lighting to grow.

Answer 4

Yes, fish and all animals get tired just like you and I. They also sleep.
