DO NOT FORGET to introduce your pair first put the female in the cup inside the aquarium where the male is so they can see each other with out hurting each other... Take the female out of the cup when the male has made a BIG bubble nest and only leave the female in the tank with the male for 1 hour at a time. After an hour put her back in her cup inside the aquarium.
GET A FEMALE APROXIMATLY the same size as your male it will make things easier for them to spawn.
MAKE SURE you know what ur doing research betta breeding before you do it to make sure you know what to expect.
MAKE SURE YOUR tank is in perfect condition to have baby fry... if your tank is not in perfect condtion your fry will probably die ... They are VERY delicate.
