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.
