No.
male
All that is needed is a male guppy in with her.
You can try to put Guppy fish in with your Betta fish. That would be one of the only fish that i would put in with my Betta fish. I say that because i have a Betta male and he is OKAY with guppies. the first guppy i put in his died to to getting picked on by him but the others did not, so just give him another chance if you decide to get guppies. Hope i helped!
She breeds with a male Betta Fish.
yes
Female guppies are larger and plainer. The male is distinctive for his long, flowing, colourful tail and generally brilliant colours.
Your betta fish is a female if she has smaller fins than an average male.
Yes they will.
the male betta fish makes the nest.
No. Betta fish will attack each other no matter the sex.
No because if a male betta is not atracked to the female they will try to reserve there territory
If the fish has a "GONOPODIUM" it is definitely a male.
