This is a BAP submission. You're bidding on two pair (2M 2F) of young adult killifish about 1.5" long. I've found these to be pretty hardy and had a high success rate from mop spawning. They're not the prettiest killifish, but they have a cool green-ish sheen when under the light. The female is plain with a black spot on the tail. They've very rare, with little info about them online. These are non-annual killifish.
