Betta fish are so pretty and colorful, they're freshwater fish so make you keep them in freshwater!@
I used to have a Betta fish!  It lived for a long time.
Oh, yes, they can live very long, although they are a species of small fishes!
I remember I was told not to put two Betta fish together.
Oh yeah that's a bad idea they would kill most other fish. Keep'em seperate!
