I remember when you had blue, red, blond (I used to know all the technical names) and greenish blue with some different coloration on the fins, some variation in the fin shape and variation in iridescence. I remember the first time I saw a black and thought that they could never get any cooler. And then a white with purplish iridescence came along. Those were the days, lol. I used to read a monthly column in Freshwater and Marine Aquarium called "Bettas and More..." where a lot of genetics was discussed. The author was Dr. Gene Lucas, who was an expert in bettas and betta genetics and one of the founders of the International Betta Congress. He discussed the potential for new color variations, but I don't remember anything as variable as what we actually see today.Yup. The candy copper, nemo copper and nemo candy copper are new color variants.
Really? You just posted that it's okay to keep a 12" knife fish in a 20 gallon long and that goldfish can be kept in a 20 gallon tank if you decrease the water temperature.That tank could be improved imo I would get natural barriers like glue bark and shrub wood things to those panels to make a natural look and maybe you could return 1 of the fish so they get more space all those fish are maybe getting 4 gallons that’s very laterally compressed
