How can you tell male bettas from female?

Answers:
Males are more flashy then females. They usually have longer tails and are usually more vibrant in color.

And no...the other poster is wrong, males don't just come in blue, green or red. They come in an ARRAY of colors. I currently have a dark red, a white and a multi-color (pink, purple, blue, turquoise) there are also many different types of "tails" the males sport.

MALES get along fine with all other fish as well...mine have been around cory's, snails, and ghost shrimp. The only fish they don't do well is like angel fish or fancy tailed goldfish...stuff that have long fins as they mistake them for other bettas

when people say"males have longer fins" sometimes this is not true.My old beta female had very long fins.one way to tell is about 1 out of every 200,000female betta fish have this, check under the belly, if there is 2 little skinny fins there, it's a boy!
