umm if i were you i'd do A LOT of research!!

it takes a lot of time, understanding, money.. etc... when he blows a nest it means he's happy... my boys do it everytime i do a water change. they love fresh clean water! sometimes its best not to try to breed every fish you have. easier to start with livebearers..
but if youre willing to buy all the extra equipment and grow ur own fry food.. then best to ya

but bettas dont have to breed.. their content not doing so
mine dont breed.. i just enjoy having both sexes anyway
