- Do you know of and understand the Aquarium Nitrogen Cycle?
I have a beautiful solid orange goldfish with a tripod tail (2 lower caudal fins, 1 upper) and 2 analfins. Tail is about 3/4 the length of the body. Body is streamline, like a comet goldfish. About 6 months ago I rescued him from a koi pond that was being eliminated. Current total length about 5 inches. I’m not sure what type of goldfish it is. Could it be a Watonai? Any ideas?
