Connor - I wasn't speaking of local hobbyist breeders per se, as almost all of them who have discus for sale will sell fish only in or around the 2" size- which I don't recommend being acquired by anyone but experienced discus-keepers who wish to grow them out in bare-bottom tanks. Also, variety (strains & colors) is always limited.
I was referring to well-regarded commercial discus importers and suppliers of high quality discus who carry large numbers of discus of several different varieties ( and many sizes) at any one time.
However, there are none very near to your location, and the only 2 of them that I would highly recommend in that category, that are nearer than most others, are Chicago Discus ( contact Josie or Miranda), or Kenny's Discus in Daly City, Ca. (near S.F. - contact Kenny Cheung). Both are excellent suppliers with top-notch reputations who sell at reasonable prices and guarantee live delivery anywhere in the U.S. - you can google for either one's website. I'd suggest Kenny, who is arguably considered the best discus supplier in all the U.S. by many discus-keepers.
