What the heck...that's the first I've heard. Buy a pair straight from a LFS and breed them right away. Patient is a must. I mean I myself haven't breed bettas yet but in 2 months I will. During the process I will obtain everything possible, prepare for jarring, food, everything. Give the pair some time to get use to their enviroment and each other. Breeding bettas doesn't have to be in a rush but should be carefully planned.
