Same person Sammy G AKA Samantha posting. The comment just posted by the other person was partly wrong. A male betta fish is the lager of male female but has many diffrent colors. The female is smaller in male female and she is not grey but she can be whites blues really any color of the males but she is a lot A LOT smaller and is not anywhere near as beautiful as the male betta fish.

Male beta fish will fight with each other. They are the most colorful with long fins. They are what most people think of when they think of beta fish. Female beta fish, plain and light grey in color, won't fight with each other, but they aren't nearly as popular.
