The Guentheri Killifish also known as the Redtail notho, is captive bred but is normally found in water holes, streams, and marshes in Africa. The term Killy is derived from the Dutch word meaning ditch or channel, not because this fish is a killer in the aquarium. These fish are ideal fish for the community aquarium, and will add some vibrant color and activity to these aquariums. The males of this species are very brightly colored, with the body having a gold to blue and red coloration. Their tail is a bright red color and the fins are outlined in black giving them a dramatic look. The female of this species are more subdued in color and form.

The Guentheri Killifish is not demanding and can adapt to a variety of water conditions. These fish prefer a heavily planted aquarium, and softer water on the acidic side.

This species of Killifish is an annual species. A breeding tank is ideal with a 2-3 inch layer of peat at the bottom. The fish will bury the eggs in the peat. After spawning, remove the peat that contain the eggs and press out any excess water. Place the moist peat with the eggs in a plastic bag or sealed jar for 3 to 4 months at room temperature. After that time period, add tank water back to the peat to hatch the fry. Place the fry in a small holding tank and feed the newborn fish live baby brine shrimp.

Guentheri Killifish will accept most live foods such as brine shrimp, white worms, tubifex, and some dry flake and frozen foods.
