I like red Discus fish types than blue types though I have more blue discus types. Only red discus I have are Pigeon Blood Discus. Even those had bad time with white poo problem. Luckily they had recovered and Now slowly getting there colors. They are not checker board discus while filling with all white strips but still very beautiful.
Pigeon Blood Discus are man made Discus fish. This strain was developed by Kitti Phanaitthi in 1991 from a mutation in Thailand. I think Pigeon Blood Discus are common than other red strains like Leopard Skin Discus, Red Turquoise Discus or Red Marlboro Discus. Probably bit cheaper too. They might not look very elegant at young age but adult Pigeon Blood Discus are super pretty .
