Description: Endler's Livebearer was discovered in 1937 by Franklyn F. Bond and rediscovered by John Endler in 1975. Endlers livebearer is a very attractive and colourful fish. Males are brightly colored, they usually have a bright orange and green, yellow or black markings, while the females are pale green in color. Males are also much smaller than the females and have a gonopodium. The males constantly harrassing the females to breed, so it is best to keep 2-3 females with each male.

Breeding is easily achived just by having males and females within the same tank. The females will give birth to live fry every 23-24 days. The number of the fry can be 5-25, depending on the female's age and size. The adult fish will rarely eat their young. The fry are quite large, and they grow fast if fed 2-3 times per day with small live foods. Males exhibiting adult colouration in only 3-5 weeks and females being able to produce young at 2 months of age.
