Chard has some good fish, just like every other breeder can't get perfect fish every time. It depends if your looking to just start breeding or if you've been breeding a long time. If your just going to start then yeah 15 bucks for a fish with a few flaws to practice with is fine. If you've been breeding a while then its purely up to you. If he has the colors you want you find a female to counteract the fins.
