Mollies (Saltwater Converted)

Saltwater‑Converted Mollies — Overview: Hardy, adaptable livebearers that thrive after gradual acclimation to marine salinity Excellent for algae control, refugium cleanup, or use as feeder fish for predatory species Available in multiple color morphs — black, dalmatian, silver, gold, and lyretail varieties Peaceful, active swimmers that add motion and utility to reef or FOWLR systems Origin & Adaptation Native to brackish and coastal waters of the Americas Tolerate full marine salinity (1.023–1.025) Adapt well to reef lighting and flow Temperament & Behavior Peaceful and social; best kept in small groups Constant grazers — pick at film algae, diatoms, and detritus Excellent for refugia, sumps, or display tanks needing algae management Livebearers — females may produce fry even after conversion Tank Requirements Minimum 20 gallons for small groups Stable marine parameters: 72–78°F, pH 8.1–8.4, salinity 1.023–1.025 Provide open swimming space and moderate flow Adaptable to both reef and FOWLR setups Diet Omnivorous — consume algae, biofilm, and small meaty foods Supplement with spirulina flakes, pellets, and frozen mysis or brine shrimp Grazing behavior helps maintain clean rock and glass surfaces Compatibility Safe with peaceful reef fish and invertebrates Avoid large or aggressive predators unless used intentionally as feeders Ideal for refugium ecosystems and algae‑control roles Why Hobbyists Love Them Inexpensive, hardy, and versatile Natural algae grazers that reduce maintenance Breed readily and provide live food for predatory species Adaptable to a wide range of marine environments
