so if you dont like your betta house him a goldfish.
Uh yes they can. bettas come in two sizes, male and female, goldfish come in MANY and if you take care of the tank knowing that a goldfish produces 1.5x the bioload sometimes 2x the bioload per fish then tropical fish they will be fine.
I respect your personal opinion on them but not the mis-information.
In my opinions no fish should be housed in anything less then 10 gallons, but thats my opinion.
