Ok we've all been there, our tank is setup, pair conditioned, everything just right and...nada.
Plants: using a live plant is a good idea, not only will it help induce your pair in spawning but it will feed your small fry until they're big enough for bbs.
Leaves: You can try indian almond leaf or banana leaves, whichever. Both will induce spawning.
Water conditioner: Well today I was at another PetCo lookin for Atison Betta Spa only to find out neither PetCo or Petsmart has it. So I was lookin at water conditioners and found out Nutrafin Betta Plus contains almond leaf extract. I'm putting in my gold HM pair tomorrow and I'll tell youif it works. But if you are lucky enough to get Atison Betta Spa GET IT. You'll have your pair spawn in a day or two. This method is MY personal favorite.
