Although their size is generally the same, there are some differences in coloration.
Both sexes of the black variety have black bodies but may also have white or cream stripes running along their sides and back.
Gold mollies have a more yellowish hue, and males of this species also have greyish spots on their back fins, giving them an attractive appearance.
Both varieties of these fish require clean water with neutral pH levels, as poor water quality can affect their growth rate significantly, leading to stunted development in the long run.

How Many Mollies Should You Keep Together?
For the best results, keeping a small group of 5-6 black and yellow mollies in your tank is recommended.
These fish are social creatures and do well in groups; however, it’s important to remember that they can be territorial when kept together in too small of an aquarium.
It is also essential to keep an eye on the size and gender ratio of the group since aggression can occur between different sexes. As a rule of thumb, females should outnumber males.

When the female is ready to give birth, she usually takes refuge in a secluded spot within the tank and releases her fry after a few days. If you notice any of these signs, your fish is likely pregnant.
It is also essential to keep up with regular water changes and tank maintenance to ensure that the gravid female and her fry are provided with a healthy environment.
