Black Molly (Poecilia Hybrid)

In countries like Mexico, Venezuela, and Colombia, there is one fish that is very popular among enthusiasts. It is called as the Poecilia Hybrid, also known as the Black Molly. The Black Molly can grow as big as 10 centimeters only. In order to live, the Black Molly requires water that has a small amount of alkaline. Moreover, Black Molly can also live in water that has a temperature of 25 up to 28 degree Celsius only.

Black Molly is also commonly seen in home aquariums as well. And it does not need a fish expert so you can breed it easily. This type of fish can simply breed while it is in your aquarium.

There will be at least 20 live young Black Mollies in a female specie but sometimes she can have as much as 60 live young Black Mollies inside. In order for the little Black Mollies to survive, your aquarium must have enough plants where they can hide. They would eventually leave the plants if they are already big enough to swim and not to be eaten by other fishes.
