Fundulopanchax avichang[2] is a species of African killifish that mainly inhabits small temporary pools of the Ecucu River drainage systems.

The species is endemic to Equatorial Guinea.

[3] Adult fish reach a maximum length of approximately 2.6 centimetres (1.0 inch).

[4] Breeding pairs of the species most often lay their eggs over the bottom, but occasionally also among the roots of free-floating aquatic plants.

Pairs stay close for some time, with just a few eggs being produced each day.
