Description

The Pacific molly is a small livebearing fish of the family Poeciliidae from the Pacific slope of Central America, from Mexico to Costa Rica. The species reaches about 7 cm and has a stocky, olive to silvery-grey body; the male has an anal fin modified into a copulatory organ (gonopodium). It occurs in a wide variety of standing and flowing waters, but prefers sites with dense algal and plant growth. As an omnivore it feeds on algae, detritus and small invertebrates. Fertilisation is internal and the female bears live young.
