Aplocheilus lineatus is currently being offered in many petshops as "Golden Wonder" or "Gold Wonder". If you see them they are the same species but have been bred in a clor variety that has enhanced gold coloration and suppressed red coloration.
Aplocheilus lineatus is a large and colorful Killifish from India and Sri Lanka, it sports glowing gold spangles and red highlights. Similar to a pike in body shape. The males have longer fins and more impressive coloration, while the females and immature males have several vertical black bars on their flanks.
This fish spends most of it's time at the surface watching out for flying insects and other live prey, and prefers floating foods. So watch out for any small bite-sized fish placed in a tank with these predators! A. lineatus prefers soft slightly acid water with a temperature range of 70-80°F (21-27°C). A tank of at least 10 gallons is adequate.

Breeding this fish is best accomplished with the Mop Method for Plant Spawning Killifish. The Natural System doesn't work well because of their predatory nature. The eggs are large and easily handled. They have an incubation period of 12 to 14 days and the fry are plenty large enough to accept baby brine shrimp as a first food
A. lineatus is an excellent beginners Killifish. It is very hardy and rather long lived for a Killifish, lasting for up to 4 years in some cases. And it's easy to spawn and raise.
