I feel like it shouldn't have been forced on anyone, it adds to the idea that bettas are disposable. Please direct all of your classmates to this site to learn about care, and let them know that they can use this site to rehome if necessary.

They all have homes lined up. They go to our prof's kids or we can take them home. Not to be mean, but in scientific terms, they are disposable.

Heres a few papers on Betta mate choice, cant find the one I found ages ago but these might give you ideas on how they determined female preference.

I am going to create an aggression index to find out the aggressiveness of a male. For one hour, I will show a male his reflection in a mirror, and will time how long it takes him to flare at it. Then I will take it out for 2 minutes and repeat for 30 trials, or until the male becomes used to the reflection ( does not flare for 1 minute of exposure). I will use this formula: a= 1- (avg. time until flare / # of responses until habituation). I think that will work, if it does not, I will have to change the formula a bit.

I have selected 6 males. Here are their scores on the Aggression Index
Aggressive male 1:0.0484
Aggressive male 2:0.0231
Aggressive male 3:0.051
Passive male 1:0.333
Passive male 2:1.14
Passive male 3:3.13

Passive male 1 is somewhat aggressive, but overall passive. Anything more than 0.1 on the Aggression Index is considered passive.

This is the figure that essentially sums up the report.
