The males have the large flowing fins and will display when they see another male or their own reflection.
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.
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.
Male betta's are more colorful then female's
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
If you have a betta fish food, and have a picture on it, it's probabily male fish. They are prettier and have longer finns. (Kinda like gold fish with long finns exept different color) The female bettas has shorter finns and are uglier, and I don't know why...Well.. male beta fish are more colorful like red and blue.And female beta fish are more whitish pink maybe with a few black spotsall i can say is male betas are colorful and females are more dull
It is pretty hard to tell. Wait until they get older then see which ones have longer fins, and shorter fins.
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
It's all in the tail. the males is larger and longer and the females is shorter.
Male betas are colorful and have large fins. Females have virtually no fins and have no color
They will normally tell you at the store- but males have longer fins than females. Males are also generally more colorful
usally femal betas will lay eggs and they`re smarter!!
