N Class Endler Fish
N Class Endlers are unique in that the strain has originated from Venezuela and have not had any hybridization. Careful records are kept establishing that they come from an original strain from Venezuela. Endlers were rediscovered by Dr. John Endler in 1975. Most of those fish were then crossed and the pure strains were lost. In recent years they have been again collected from Venezuela, which is how N Class Endlers strains were established. There are many types of N Class Endlers.

Received the N Class Endlers and they arrived healthy. The males show vibrant colors, though they vary slightly from the photos. They are active and seem to enjoy their tank environment. A great addition to a small community aquarium.
Isaac Hunter –
The fish are lively and colorful. I noticed some variation in color between individuals, which is expected. They are smaller than guppies, as described. Easy to care for and maintain in a well-balanced tank.
