The Rachovi Killifish, also known as the Bluefin Notho, is captive bred but is normally found in temporary water holes, ditches, and marshes of 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 blue and red coloration with vibrant blue, red and black tail and fins. The female of this species are more subdued in color and form.

The Rachovi 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.

Killifish have some unusual rearing techniques. 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, and place the moist peat and egg mixture in a plastic bag or sealed jar for 4 to 6 months at room temperature. After this time, 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.

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