yes, he can wait apx 16 days after first breeding
Yes all bettas can mate with other bettas. " regular betta fish" there are different types and they can all breed together.
Betta's are pretty good with other fish, it's rare that they will fight, maybe with other betta's
Bettas don't form pair bonds like some other fish--notably cichlids--do, so you can breed your female to the male you already have.
Well Betta breeding is tricky, some betta keepers are "ok" but others are NOT, your betta keeper must have a seperater to separate the male from the female. You must do this so the male can get use to the look of the female.. After 1-2 days put the female in with the male.. And watch them, if they fight then you will have to separate them again.
If they are not too old and the female is ready, then they will mate.
it doesn't because it is not a human. he only needs a bubble nest. female bettas make eggs to be placed into them by the male.
Yes they can; it's not typically about the colours, but whether the male will build a bubble nest for the particular female you are trying to breed him with.
they build it to mate even if there is no female Betta the male builds by instinct and a change in water triggers it. hope that helps.
NO female bettas do not fight each other
No.
to make more bettas
It means they are getting ready to MATE
