All fish were active and swimming in their bowls. There was a small amount of leftover food from yesterday in all but male #5’s fishbowl. Tanks are still clear. The self-trials for the males will be continued today during the regularly scheduled class period (12-1:45 PM). All tanks were cleaned after the trials were completed.

Important Terms to Remember:

Gill Flaring: an ocular display with the extension of the gills. This is honest signaling because the fish is unable to breathe during this display and this indicates the fish’s fighting ability and strength.

Tail Flicking/Beating: when a betta attempts to hit the opponent with the large colorful tail. It is thought to be associated with courtship rituals and is hypothesized to occur more frequently when there is a female bystander.
