For breeding, do a LOT of research. Then make sure you have ALL your supplies. Have a goal in mind. Not saying this to discourage you. Just want you to be ready. Also keep in mind how many fry can be produced and think about how you will rehome them. Personally, I don't breed petstore fish because of the chances they have bad genes. I like to know the background of a fish.
Honestly, it wont hurt her to not breed. She may simply reabsorb the eggs. If not, she will likely release them. In the case that she releases them, she will likely eat them. Should she eat the eggs, you may have to fast her for a day or more to avoid overfeeding her.
