Question

plz help meee ohhh and thank you!

Answer 1

females are just as colorful as the males, here is my tank of females: http://img157.imageshack.us/img157/7732/females0vp.jpg
and one that shows female finage:

each female is circled in red, and there is another white and teal one hiding.

males are long and thin with long flowy fins. males also have a "beard" at their gills that they puff out.

females have shorter fins, but are just as colorful. they are usually quite plump as well and some develop a hump type thing if they get big enough. the alpha in my tank is the huge teal one at the top left, she has a very big hump.

hope that helps.
here is also a site on sexing bettas:

Answer 2

Well generally males:
-Are long finned (Of course Thai fighting lines have short finned males.)
-Flare at a mirror
-Are more colorful

Female
-Are shorter finned (Of course Thai fighting lines have short finned males.)
-Don't often flare at a mirror, but fade in color and develop dark bars. Note that female can and will flare at times, but it's rare.
-Are less colorful, but keep in mind a female can have all the same colors as a male. If well fed and not stressed they are every bit as colorful as the boys. In the store they often look pretty drab.
- Have a white ovipositor on their under side. Some males can have this too. (So I'm told my males never have.)

Answer 3

Females are NOT grey! Females come in the same colors, patterns, and combinations as males. Nor is it illegal to sell females. The way to tell them apart is the females have a white ovipositor sticking out of their vent. Its tiny and sometimes hard to see, but that's how you tell. Females are also more likely to show horizontal and vertical stripes when stressed or excited.

Answer 4

Store bought males typically have long fins and brighter coloration: http://www.aquariarieti.it/public/publishing/Betta%20Splendens(03102005at131836).jpg

Females have shorter fins and typically are more drab, but that's not always the case: http://www.labyrinthfische.de/assets/images/autogen/a_Betta_splendens_Khonburi_Weib_7k.jpg

There are a few instances of short-finned males being sold as females.

Answer 5

The long fins are boys. The short fins are girls and they might even be difficult to recognize as Bettas if you don't know what you are looking for. Boys put together will fight to the death. Girls put together will be just fine. A girl put in with a boy will chew off his fins until he doesn't have anything to swim with.

Answer 6

they breed very nice females now so its a lot harder to tell -- some males get accidently sold as females if their fins are shorter. when they are grown females have little spots on their undersides that are where their eggs come out. i can't find a picture of it.

Answer 7

beta males are the bright colorful ones usually bought at the pet store. females usually are not sold and dont have the long waivy fins os as colorful

Answer 8

Male bettas are very colorful and have fancy tails.Females are kinda plain.Not as fancy.

Answer 9

The male looks prettier, with the longer tails, female, not as pretty...

Answer 10

females are the ugly smaller ones, and the males are big beautiful and have the flowing fins.
