Gunther’s black seedling

This brightly coloured killifish lives in small savannah pools and streams on the Tanzanian island of Zanzibar on the east coast of Africa. The ornamental fish species is very popular in aquariums. In the wild, killifish do not grow very old, usually only a few months. In aquariums they can live for several years if kept under optimal conditions.

What distinguishes Günther’s killifishes?

The fish are best kept in a species tank. They generally behave peacefully towards other fish, but only as long as they do not cause any restlessness or hectic in the tank. Very active swimmers do not like them at all. Günther’s Prachtkärpflinge love it rather quiet. They also socialize well with larger shrimp (from 4 cm) as well as snails and mussels.

In small groups of at least eight to twelve specimens with a surplus of females, where one male should be followed by two females, Günther’s Gorgeous Shrimps feel particularly comfortable. The constantly impressive males are territorial and often behave aggressively among themselves. Also the females have nothing to laugh about. They are often strongly driven by their male conspecifics. There is a strict hierarchy within the groups.
