Description: This is one of the most beautiful livebearers, and it should receive more attention. Typically the fish is silvery-green with patches of yellow, blue, and black. At firsh glance, it looks like a wild guppy, but it is a bit more streamlined and its tail is not so large. The base colors yellow, blue and black are always present in the males. Swamp Guppy has a red color variant which body is orange-reddish with some black spots. Females have drab gray coloration. Older females can show golden/orange areas on the belly.
Males are more colorful, have a gonopodium and a smaller more slender body. Provide the breeders with small mosquito larvae and Drosophila. Embryos can make up 25% of the weight of the female. Usually 11 -25 offspring are produced. The fry are predated by the adults, therefore a separate birthing / raising tank is required.
