One of the most common freshwater fish in the aquarium hobby today, and quite often the most unusual, is the Black Molly. Unlike the other types of Molly fish available in the fish keeping hobby, the Black Molly gets the majority of it’s traits as a result of captive breeding, and you would struggle to find one in the wild.

It’s pretty obvious where the Black Molly gets its name from, but what isn’t as obvious is how they came to obtain such a dark, distinct color.
