The Black Molly is an excellent choice for the home aquarium as it is hardy and easy to care for. It is best kept in tanks of 30 gallons or more, with plenty of strong plants to provide hiding places and a healthy environment. A good filtration system should be in place to keep up with their hearty appetites and the resulting waste products. The Black Molly is a peaceful fish and can be kept with other peaceful, large fish that can tolerate the same water conditions. It is a great addition to the community tank, adding both beauty and activity. Furthermore, they are relatively easy to breed and will make a great addition to any home aquarium.
The Black Molly is a species of fish with distinct physical differences between males and females. The male has a pointed anal fin and a much larger dorsal fin, while the female has a rounded anal fin and a pregnancy spot. This makes them easy to identify. To promote successful breeding, they require a 25 gallon or larger breeding tank with a thick algae mat and densely planted plants. Additionally, having a group of floating plants in the corner of the aquarium will provide a safe haven for the young fish when they are born. On average, the female gives birth to 10-60 young every 60-70 days, and these fry are already about half an inch long.
The Black Molly is an omnivorous fish that prefers both meaty foods as well as algae-based flakes. Provide these fish with an algae-based Flake food, as well as freeze-dried bloodworms, tubifex, and brine shrimp.
