  • Keep in an appropriate size aquarium; provide plants for hiding, various species may prefer sparse or thick vegetation.

The Molly is generally peaceful but an active swimmer. These social fish like to be kept with their own kind or at least with members of the livebearer family. The males will occasionally squabble amongst themselves but generally without any damage done.

They are livebearers which means that the baby fish come out free swimming. Like their livebearer counterpart, the guppy, the Molly is a prolific breeder and a female will give birth about once every 28 days. 

This fish is considered a good community fish. In general, Mollies are peaceful, though it has been noted that behavior is very individual. Some Mollies are markedly more aggressive than average. Males will establish a clear hierarchy and more dominant individuals might extend the hierarchy over other tankmates.

They will eat most fish foods including flakes, frozen, freeze dried and live foods such as brine shrimp.
