How do i tell if my Betta fish is a boy or a girl?

Question

Answer 1

Typically if it is betta splendens (the regular betta you get in a store) the males have long, flowing fins http://www.cacentre.com/avatar/02betta.jpg and the females do not http://www.flippersandfins.net/Images/BettaFemaleBars.JPG

Answer 2

If you have two to compare with, it'll be easy to see because males usually have longer and more showy fins.

However, with the competition quality bettas we have today, some females are developing such long fins, they almost look like juvenile males.

The other thing you can do is to look under the fish's stomach. If you see a tiny while spot that looks like a single egg, that's a female and it shows that she is ready to mate. Males don't have that.

Males also tend to develop the habit of building bubble nests. So if you see your fish doing this, it's definitely a male.

Most bettas sold in the fish stores are male anyway so it is unlikely you ended up with a female. Females (except very high quality ones) tend to all be crowded into a tank. They scuffle but do not fight to the death like males.

If your fish was on its own in a little bowl at the petstore when you got him, then he's most probably a male too.

Hope this helps. Good luck.

Answer 3

If your betta has long fins (around 1 inch long) that is a male. If your betta has short fins (less than 1/2 inch long) it can either be a female or a plakat (short fin) male. Look for a white dot in front of its anal (bottom) fin, if its there thats 100% a female. If its not there it is most likely a male or just simply a young male (their fins show their true colors around 8-10 months of age). Colors do not mean anything. Both males and females come in various colorations.

Answer 4

Male betta fish have the long fins and are often really bright colors. They're usually the type to be sold in pet stores. Female betta fish are more dull in color and have short stubby fins.

Answer 5

Does the fish have a huge, colorful tail? If it does, then it is a male. Usually, stores just sell male bettas because the females are used for breeding.

Hope this answers your question,

Answer 6

like the bird kingdom - the Male species are the most pretty - an example would be like the Peacock, the robyn - The Males Betta's are the most vibrant in colours and have the longest fins and decoration - just beautiful -

Answer 7

Males are also larger than the females, and are more agressive, so that you can only have one in a tank unless you use a 'betta barracks' to keep them separated. Females are not agressive, so you have can several in a tank without problems.

Answer 8

does it have long fins? Females tend to have shorter, less majestic fins, while males have big beautiful ones.

Hopefully this helps!
Also you can ask someone at the pet store you got it at.

See the difference in the fins? That's all there is too it, males have larger and longer fins
