Molly
From Microcosm Aquarium Explorer
The common Black Molly, a brackishwater fish that is available in many color forms. Aaron Norman
Overview
The Molly is a hardy, stocky bodied (spheno = “wedge shaped”) species that, unlike its sailfin counterpart, lacks the elaborate dorsal fin. Because they are often found in mangrove swamps, estuaries and many other “salty” environs, some saltwater hobbyists use molly fry as food for their fishes, because of the molly’s ability to do well in saltwater tanks. Breeders have developed many color strains, including marbled, orange and blue forms.
Family: Poeciliidae
Other common name(s):
- Black Molly
- Mexican Molly
Native range:
Habitat: Mollies will acclimate to the typical community tank water parameters, but adding some aquarium or sea salt to the water (1-2 level teaspoons per gallon) will ensure a healthier slime coat, and for most other fishes this will not be a problem.
Maximum length: 6 cm (2 in)
Minimum aquarium size: 114 L (30 gal)
Water: Freshwater 22 °C (72 °F) - 26 °C (79 °F)

Feeding
Omnivore. It is important that their diets not only include meaty prepared foods, but also lots of plant matter, such as algae wafers and Spirulina-based flake foods.
Aquarium Compatibility
Acquire one male to several females to reduce the male’s harrassing any single female.
Breeding/Propagation
Mollies are livebearers that tend to be less prolific than their counterparts.

Notes
Keep with other peaceful community tank fishes.
