The striped panchax (Aplocheilus lineatus) is a species of killifish, of the genus Aplocheilus. An aquarium variant of this species with a more yellowish coloration is known as golden wonder killifish. The striped panchax inhabits fresh and brackish waters of India and Sri Lanka. It is found in streams, rivers, swamps, and paddy fields. This fish grows to a length of 10 cm (4 in). Most male A. lineatus measure around 7 centimetres (3 in), but the fish can grow up to 10 centimetres (4 in) under excellent conditions, especially if brought to the end of its life expectancy, around 6 years. It possesses a parietal eye which permits it to see prey insects and predators above it on the surface. A. lineatus can jump very well.
