Overview
The plumed lyretail is a mostly peaceful killifish for a planted species tank. It takes some experience to keep well.
Did you know
The plumed lyretail hedges its bets by laying eggs in two places. At least some eggs survive whether the pool dries out or not.
Caring for the plumed lyretail
Keep plumed lyretails as a trio or a small harem in a species tank of 20 gal (75 L) or more. A well planted, dimly lit tank with floating cover and a firm lid suits them.
Keep the water soft and slightly acidic, at 68 to 75°F (20 to 24°C) and a pH of 6.0 to 7.0. Feed live and frozen foods such as bloodworm, white worm, brine shrimp and daphnia. They accept some dry food as well.
Plumed lyretail males show off to each other but rarely cause real harm when there is room and cover. They are bright, with rows of red spots on a blue-green body and extended, lyre-shaped tail points, while females are tan.
The plumed lyretail is a switch spawner that can lay eggs on plants or in the substrate, depending on conditions. Spawn it on fine plants or coconut fiber. Its eggs do not need to dry out completely, so incubate them damp, usually for six to ten weeks before wetting triggers hatching. Breeding it is a moderate challenge.
Good to know
The plumed lyretail, Fundulopanchax filamentosus, is a non-annual killifish in the family Nothobranchiidae. It lives longer than the true annual species.
In the wild
The plumed lyretail lives in small, often shaded pools, ditches and slow streams in the coastal lowlands of West Africa. Its range covers shallow forest and savanna waters in Togo, Benin and southwestern Nigeria.
