This video was made by a beginner for sure. Most of the "strains" mentioned are generic names made up by breeders. You could have atleast explained about the difference between wild and domestic discus.
A famous breeder in Penang once told me that back in the late 90's, Japanese buyers were willing to pay USD2000-2500 for one high grade adult Leopard Snakeskin 😳I knew a few exporters who were making a killing out of discus trade but lost much of it to excessive spending and gambling
