Because i am curious what other people think. I only pointed out that the argument could be made about any fish in any tank. i never said anyone's opinion was wrong. i have mine. You have yours. The reason I made the poll about Bettas specifically is because from what i read they are the most commonly debated as far as the space they are given. From what I often see anyway.then why did you bother making a poll?
do some research.
No need to do research. The poll is the best way I know to find out what the popular opinion is. research won't tell me that.
