Endemic to the Río Atrato drainage in Choco and Antioquia departments, northwestern Colombia, where the full extent of its range is somewhat unclear.

Green Swordtail
March 13th, 2012 — 1:18pm
Wild swordtails are a fairly basic green colur. However the vast majority of swordtails available in the hobby today are hybrids of X.helleri with X.maculatus or X.variatus. There are a huge number of selectively-bred varieties available, including wagtail, lyretail, tuxedo, albino, neon, red, green and hi-fin.

One of the most popular aquarium fish in the world, the guppy is instantly recognisable to most people. There are many aquarium bred varieties of this species available, most have elongated finnage and gaudy colouration. The wild form is seldom seen for sale. Unfortunately many commercially bred guppies are not very hardy due to inbreeding and over-production and are prone to disease and premature death. We therefore recommend the purchase of quality stock from breeders or society auctions.

Aphyosemion striatum – Red-striped Killifish (Haplochilus striatus, Epiplatys striatus)
The default photo isn't indicative of how most populations of A. striatum look like in reality. That is a very washed out looking male in my opinion. ...
