Aggressive behavior: Going head to head with a betta.Featured science projectScience project video


Day 1

  1. Place a mirror in front of the aquarium glass so the betta can see it.
  2. Observe the reaction of the betta. The betta should display aggressive signs (Refer to "Betta Splendens Aggression," located in the bibliography section).
  3. After the betta displays aggression, remove the mirror. Wait for 1 minute then present the mirror again and observe the betta's reactions, paying attention to any changes in the display behavior.
  4. Repeat this process until the betta shows little or no interest when presented with the mirror. Make sure to note the number of trials so that it may be entered in the data sheet. Each time you present the mirror is one trial of the science experiment.
  5. Record the number of trials in the data sheet.
  6. Discontinue the experiment till the next day.
  7. Create a hypothesis of what you think will happen the following day when the betta is retested. Write your hypothesis as " If I repeat the experiment on the second day, the betta will take ______less, more, or the same number___ of trials before it's response to the mirror diminishes.

Day 2:

Repeat your science project experiment and record data. Compare the results of day 1 and day 2. Were the findings of day 2 consistent with your hypothesis?
