Discus Fish colors
There are 4 'real' discus variants, with their own Latin name. The rest of the color variants are captive bred and the list of these color variants is nearly endless. They have exotic names like, 'Snake Skin', 'White Diamond', 'Blue Diamond' etc... The color variants displayed here are just a few examples, more will be added in the future.
