thats cruel to keep bettas like that, they are also called simease FIGHTING fish, they are called that for a reason. putting two right next to eachother for entertainment is just sick. actually it's a 0/5, the lowest it went was 1.
Well.. 22 now, living in Chicago, Haven't had any fish in a while, except for my female Betta, who passed away earlier this year.
You need to chill out. okay, this was taken however many years ago, but I'd like to point out, as said in the comment, the bettas didn't live in there. I put them in there temporarily- I used it to take up close pictures like the ones in this gallery. They were never in contact with each other. And don't go out pretending its cruel and unnatural for creatures to encounter other members of their species.
