Help Identify the Killifish

[alekograph]

Hi All, they sold me this fish as Golden Wonder Killi, and I can't figure out the species.
You will see in one of the photos with a male and female bluefin killifish for comparison.
The fish measures about 2 inches, its honey color with a long black stripe across the body.
Please help ID this fish. Thanks in advance.
