For a long time Betta Fish have been put in below mimimum sized cages for the rest of their lives! 
Then of course... Pet stores profit from it!
On Petco's website they say that the "miminum" tank size is 1/4 gallon! See for yourself if you don't believe me! https://www.petco.com/content/petco...ervices/resource-center/caresheets/betta.html
Why are Betta's mistreated? My theory is that people THINK betta fish make good beginner pets because they have been mislead by common betta fish mistreatment and see them and think "OH THIS PERSON HAS THEM IN A 1 MILLILETER TANK! THAT SOUNDS LIKE A GOOD IDEA! OH AND THE PEOPLE AT THE PET STORE SAY THAT 1/4 GALLON IS FINE!" (1 day later) "OH HI DEAD FISHY!"
Anyways see ya later.
