Black Lyretail Molly

Black Sailfin Molly
Poecilia latipinna var. 'Black' or Poecilia velifera var. 'Black'

Key differences: Guppies are generally smaller, have a more slender body profile, and males exhibit highly variable and often elaborate caudal and dorsal finnage that is distinct from mollies. The head shape is also subtly different.
