if they are colored i dont think they wold be having that red designs. and look at the anal fin look at the red on there. for them to artificialy color a fish like this more than likl the fish would be dead before they got done. i think its just a long line of artificial selection and inbreeding
You know I did see some larger severum at one of my LFS that had almost the same coloration to them.. Thought I didn't pay any attention to them because I figured they were just Golds with a bit more red than usual.. They were rather nice looking though.
I saw some brightly colored golds at my LFS, the ones that didn't sell after a month however all their orange and red flecks disappeared? They looked back to normal..hormone induced foods maybe?
