The Bluetail Goodea, also called the Striped Goodeid or Splitfin, is native to creeks and drainage areas of a limited area of central Mexico. It is highly endangered by pollution and by drainage of marsh land. The tail is often clear but males develop blue tails when breeding. The dual stripe along the flank giving the alternative name is not always clearly visible.

The only species in its genus, when the stripes are not clear the fish, particularly the female, can resemble the Goldbreast Goodeid/Splitfin Ilyodon furcidens, but the tail on that is very differently marked. She is a "live-bearer", ie gives birth to live young rather than eggs. Males grow to 7cm and females to 10cm long.
