Can Fish Tell Time?

Can Fish Tell Time? | Science Fair Projects | STEM Projects
Have you ever wondered if fish can tell time? This science project will explore if aquarium fish can anticipate feeding time and if their biological clock can be altered.


The hypothesis is that aquarium fish can anticipate feeding time and their biological clock can be altered.

Method & Materials

You will create a feeding schedule, observe the fish's location at feeding time, and change the feeding time to observe the fish's behavior.
You will need aquarium fish, an aquarium, fish food, and a timer.


The results of this experiment showed that the fish were able to adjust to the new feeding time after a few days. An interesting observation was that the fish seemed to anticipate the new feeding time before it was due.

Why do this project?

This science project is interesting because it explores the biological clock of aquarium fish and how it can be altered.

Also Consider

Variations of this experiment could include observing the fish's behavior when the feeding time is changed multiple times or observing the fish's behavior when the food type is changed.
