What Is A Black Diamond Koi?

The black Diamond variety looks a lot like the black Zeus variety, but you can tell them apart by their scales. The black Zeus has larger, uniform Aragoke scales from a scaleless background, giving it a unique look. In contrast, the black Diamond’s Aragoke scales come from a fully scaled family. This results in smaller, uneven scales that can sometimes include normal-sized ones. This mix of scales can make the black Diamond look a bit like a regular fully scaled koi, but they are slightly larger, helping to create unique features that set these two varieties apart.
