Betta fish are hard to breed. The female can not be left with the male for too long cause he may kill her. Not many people raise them cause finding 5 gallon aquariums to house each adult is hard. The babies will do fine in a 1 gallon for a while, but they need a heater to survive. Without one they become weak and susceptible to illness. Where are you gonna put 100+ fry? It is best to start with guppies...
