Yucatan Molly

Yucatan Mollies are omnivorous and should be fed high-quality flake food or pellets as a staple, supplemented 2-3 times weekly with frozen foods like brine shrimp, daphnia, or bloodworms. Include vegetable matter such as blanched spinach or spirulina-based foods weekly to support their digestive health. Feed small amounts once daily, only what they can consume in 2-3 minutes.

Yucatan Mollies are peaceful, active swimmers that spend most of their time in mid-water zones, though they will explore all tank levels. Males are notably territorial and will display their impressive sail-like dorsal fins to establish dominance, but rarely engage in aggressive combat with other species. They are social fish that thrive in groups and benefit from the presence of their own kind, though they can be kept singly in larger tanks.

Breeding Yucatan Mollies in captivity is moderately difficult and requires pristine water conditions with high pH (7.5-8.5) and temperature stability. Females are livebearers that produce 20-100 fry every 4-6 weeks when conditions are optimal; fry are relatively hardy but require fine foods like infusoria or powdered flake initially. Separate fry into a nursery tank to prevent predation by adults, though some fry will survive in heavily planted main tanks.
