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.
