Yeah, I'd run away from that deal. Those guys look severely stunted. You can tell by the 'football' shape they have. Healthy discus should be nice and round. It takes a lot of effort to raise discus the first couple months to ensure they grow properly. And that's not something that LFS will do, or even breeders with low quality culls. I'd spend more for fish from a reputable source, or spend a little more and buy them as adults.
