Need help in identifying fish

[davestial]

Hi all,

I would need some help in identifying this fish.

I was suspecting that it might be a halfbeak but would like to engage the experts in this forum to help me.

Aplocheilus panchax, a killifish, and the one in the picture is a male. Where did you get this?
