Reproduction 

Mollies are live-bearing fish that can be easily sexed as males and females. Female mollies often need plants to provide them with hiding spaces from the persistent, male population of other fish for their fry to survive. When breeding mollies, the male uses a modified anal fin to inseminate the female. The eggs are fertilized inside of her and then she carries them for 60 days of gestation before they hatch. The female molly will then give birth to about 20-50 fully developed blackfish. If Mollie’s parents are solid black at birth, the fry will be too!

Diseases 

The viviparous are fish prone to attack by fungi, white spots,s and other diseases associated with parasites. However, the most common in the Mollies is the so-called “Mollies’ disease”. Caused by the bacterium Columnaris, Flavobacterium columnare, which causes deformation in the fish column.

It can be detected that the fish have been attacked when we observe a change in the skin.
