I wish my mom would let me get a Betta. It wouldn't be much different from about the fifty million pets I have.
Also, this is really new, I thought Betta's needed their own separate tanks, or they'd kill other fish? Your Betta must be... Mixed with something else. My aunt had a Betta, which killed all her tetra's and guppies in her twenty gallon. Originally, they called Betta's, 'Siamese Fighter Fish', but changed the name to something more lovable.
