You are bidding on a pair (1M 2F) of Blue Snakeskin Endlers. Overview: Small, beautiful, active, hardy, peaceful and prolific, Endlers are an ideal nanofish. First discovered in 1937 and then rediscovered in 1975, they were very scarce in the hobby and did not become well established in the aquarium industry until a couple of decades ago. Now, Endlers and Endlers/Guppy hybrids can be found in a vast array of color patterns and fin shapes. And this is just the beginning. New varieties are continuously being developed.
