Females have short fins compared to males apart from the wild species and the plakat and halfmoon plakat.
Females have an ovipositor; a white raised bump just behind the ventral fins.
The ventral fins are usually shorter.
They display vertical bars when stressed which aren't as visible on males.
They show horizontal bars, usually called breeding stripes when keen to mate.
The male of the species has brighter colours and is a much larger fish than the female
look at the color... if its bright and colorful its a male. if its colorless its a female.
Well, if you mean a Siamese fighting fish (betta splendens) the male are always bigger than the females, and usually the males are more colorful. The males have large tails, as the femaleshave small tails and dorsal fins.
the male well have made a fairly big bubble nest i think I am going ta try breeding
If you have both a male and female in the tank and you see eggs, then it did lay them.
Feeder fish, How do you tell male from female of the?
it fat on the left side Try feeding her a pickle. :P Better yet, visit the number one beta site on the web... http://bettatalk.com/ Enjoy!
No, I wouldn't recommend it. Bettas can be very aggressive, hence the name Siamese fighting fish.
Males are larger and have much more colorful and have larger, more elegant fins. Females are small and much less colorful. also, females will not fight each other while males will.
A marine fungus called "Ick" by professional tank cleaners. It's lethal if not treated. Call the fish store nearby, tell them about this, and lay out the surprisingly realilstic amount of green to get the medications. Then fix this. While not 100%, you shuld have a good chance of saving the fish.
you can tell if one of the female fish has a puffy stomach a female has a big shape of a V and a male has a smaller one.
If your fish is a fighting fish it will be still for most of the day and probably attack another fish who wanders into his "territory". Fighting fish often come in bright colours like red or blue. But some fish are just naturally aggressive and hurt or kill your other fish! {trust me I've experienced this } It's very important to know the difference between a aggressive fish and a fighting fish. If you still can't tell talk to your local pet store or talk to an expert.
