Male betta's are more colorful then female's
The bright colored betta is the male. The males have to be pretty to attract the female. That means the light colored betta is the female.
you can tell if its a boy or girl by the fins the male Betta has long fins and the female Betta has small fins
usally femal betas will lay eggs and they`re smarter!!
Male betas are colorful and have large fins. Females have virtually no fins and have no color
The male Plakat is still a male Betta splendens (although its fins are not as showy) so it will display when shown itself in a mirror. A female Betta will not display.
A female betta has very small fins with a long body while the male betta have lots of nice flowing fins.
The males have the large flowing fins and will display when they see another male or their own reflection.
The males have much more elaborate fins while the females are rather plain. Also, if you put a male in an aquarium right next to another male betta, it will become agitated and attempt to fight. A female would not.
A girl Betta is dull and not as pretty as the male. But, a boy Betta is colorful and pretty to attract the female mate.
Nothing will happen but if you put a female betta fish and a male betta fish their going to figth so make sure to have that thing that separates them male betta fish can figth and if a male betta fish has babies separte them and keep them away from their parents and when they grow up check if their a male or a female if their female put them on the same tank put there might be a lot of females if i was u i will just sale them cuz i think you only have one tank but thats my opinion and if somebody needs a question just tell me my name is Allison Hamilton
The male Betta splendens is a larger more colourful fish with much larger showier fins than the female. He will also flare up almost immediately when he sees his own image in a mirror. The females do not do this so readily.
The female has shorter fins than the male and is generally less colorful. They should be labeled at the pet store. The females are usually less expensive, too.
