When a female Betta is introduced to a male Betta one of two things will happen. The male will build a bubble nest and try to spawn the female and during the courting time he will drive off any other occupants of the tank and kill them if they can not escape (hide successfully). He does this in order to protect his prospective young. If she fails to spawn he will drive her off and kill her if she is not removed. In other words you can not keep a male Betta with another Betta (male or female) without trouble. The Tetras will be perfectly OK with a Betta female OR a Betta male. Not the two (pair) that you are proposing. The general rule that all experienced and successfull aquarists live by is a fish needs 1 gallon of water per inch of body length. Work it out.
The problem will not be the tetras coexisting with the Bettas. It will be the female Betta. She will undoubtedly be killed by the male. He may well spawn her first but afterwards, if she is left in his presence he will kill her. Also if he has ova or fry to look after he will kill the tetras in defence of his young.
Female beta is a murderer.
Male betta's are more colorful then female's
From a female Betta. Then the male Betta fertilizes them when they breed together.
Your betta fish is a female if she has smaller fins than an average male.
If they are not too old and the female is ready, then they will mate.
She breeds with a male Betta Fish.
it depends i have a male with a female betta, in a 2.5 gallon tank,they get along, i wouldnt risk it, no
the female betta fish are released from a vent while a male embraces her
If you would like to know what gender your betta is, look for the egg spot. (for females) It should be a small white cloud between the head and body. If your betta has one, it's a female. If your betta doesn't have one, it's a male.
no because male betta's are really aggressive to other betta's which plakats are male's. but female betta's can stay with other females. don't try to, one of your betta's are going to end up dead.
