I am very interested in the color morphs of freshwater fish and I am wondering if anyone knows much about color morphing and which fish in the trade are color morphs.
i would believe someone decided to raise the "mutated" ones and liked how they looked and kept breeding more of the same to eventually get the end results.
Like pink and marbled convicts or flowerhorns.
The Philippine Blue Angel fish variations created by Ken Kennedy is a good example of new morphs that is creating a huge excitement among tropical fish hobbyists.
