I would avoid buying discus from LFS/LPS, due to the markup. Breeders are the best and cheapest source. I bought 3" discus at $20 each from a breeder, where an LFS/LPS would have sold it to me for about $50. It's your choice/money, so if you still opt to buy it from an LFS/LPS, be it.
Also, there's the
GCCA classifieds, where people often sell their discus.
BTW, I forgot to contact Larry. I got side tracked last time. I'm doing it now as we speak.
