These fish are fine in community tanks as long as they are not overstocked with many other fish. Mine seems fine with about 20 other fish though. They eat flakes, pellets, and frozen food. This one loves blood worms. Make sure you feed them some flakes and or pellets with vitamins and minerals too though to maintain good health.
As with all livebearers, they are prolific breeders and are best kept in a “harem” ratio of one male to two or three females. This allows the females to have some relief from the males’ constant pestering. Males have a modified pointed anal fin known as a “gonopodium” while this fin is held fanned out in females.
Mollies are generally brackish water fish, meaning they like a salt level between that of true freshwater and full saltwater (usually with a specific gravity of 1.005 to 1.015). While they can be acclimated to freshwater, they still should have a higher pH – around 7.4 to 7.8 – and will benefit from some aquarium salts. My tank is lightly salted at about 1 tablespoon per 10 gallons.
Lot Size: 6
Male to Female Ratio approximately 1:1.
