About Endler’s

Breeding Orchid Endler’s Livebearers has been a wonderful and exciting hobby. Using documented Class N Orchid Endler’s, I am able to provide these hardy livebearing fish to others for the ultimate in freshwater enthusiast conversation starters. Nothing is more spectacular than the bright, bold colors of these rare fish, believed to be extinct in the wild. By keeping genetic diversity as a high priority, myself and other keepers and breeders will ensure these small fish will grace freshwater tanks for beginners and experts alike for years to come!

When categorizing Endler’s Livebearers, it is important to remember that only Class N Endler’s are considered “true” Endler’s. These documented fish have not been hybrid with other species, and their genetic heritage can be traced directly back to the wild. It is important that anyone interested in keeping these creatures as pets purchase their fish from reputable breeders and keepers. In other words, ask for their documentation!

Endler’s Livebearer’s first collected by Franklyn F. Bond during the 1930’s in warmer harder water than many of the other live bearer’s that normally prefer cooler water temperatures. Later during the 1970’s Professor John A. Endler collected the Poecillia sp. in the northeastern part of Venezuela in the Laguna de Patos. The Endler’s Livebearer didn’t receive its common name until the 1980’s when colleague Dr. Kallman introduced the “Endler’s Livebearer” or “Endler’s Guppy” to the German aquarium community.

A classification system has been created so that the type of Endler’s and the origin is easily distinguishable to hobbyists. Any Endler’s Livebearer that can be traced to their native waters in Venezuela are considered ‘Class N’ Endler. Any Endler’s Livebearer of unknown origin appearing to be an Endler’s Livebearer based on its size, shape and color will be considered ‘Class P’ Endler. Any Endler’s Livebearer crossed with any other livebearer will be considered ‘Class K’ Endler.

Endler’s Livebearers are becoming more common in the hobby, and gaining popularity thanks to their wild, psychedelic coloration and ease of care.

The Endler’s Livebearer requires an aquarium with at least 20 gallons of water and is very tolerant of changing aquarium conditions. Plants should be hardy varieties such as Java Fern and Java Moss that can handle the increased hardness in the aquarium. Other peaceful fish would make good tank mates.

The Endler’s Livebearer is an omnivore and requires both algae-based foods as well as meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp will provide guppies with the proper nutrition

When trying to determine if you have a male or female fry, the most reliable method is by looking at the anal fin on the underside of the juvenile fish. Females will have a rounded fin which cannot be extended. Males will have a pointed fin which can be extended forward. This pointed anal fin on the males is called a gonopodium. More easy to see is the bright colors which males have once they are adults. The development of the male fry’s gonopodium can start as early as 3 weeks of age, to as late a 8 weeks.
