I mixed red rili and blue rili together, but to be transparent I had no clue what I was doing. Within a few months I had many wild variants. So I began to cull the wilds, but they reproduced so quickly that it was impossible to keep up. So I just quit and let them go without culling. That tank is now almost three years old and I would say that 70% are a wild type, 20% look like true rili and 10% have develop very interesting and unique patterns. I just recently started catching out tiny babies and putting them in separate tanks to see if I can maybe make something interesting.
