I hate to say anything bad about Kris, but as he's not the breeder; as Phil said, the fish is deformed. That is what's commonly referred to as "pinched head", very common deformity in inbred fish. Breeders used to cull those fish, but since people will pay top dollar for unique/weird patterns, they are becoming more and more common in the trade. Pair that with the influx of at home breeders and we get more inbred fish as many people buy their pairs from the same breeder's broodstock. To counter this, none of my brood stock are from the same breeder or pairs.
