well iv had bettas for about 5 years now but iv never thought of breeding them till now.i just want to know how long it will take for a male to start blowing his nest once he is introduced to the female. if he dose start blowing his nest that means the two fish r compatible right?????? its been about a day and a half and he keeps wagging his tail at the female and everything. but still hasnt even started on a bubble nest??????
