How long do killifish live?

Killifish live between two and five years in aquariums. Their living conditions directly affect their likelihood of living longer lives.

Killifish require a clean tank with a tight lid (they are jumpers), a water PH level of between 6 and 7, rocks, floating plants, a balanced diet, a water temperature of between 72 and 75 degrees Fahrenheit (22 and 23 degrees Celsius), and a water hardness of 122–162 parts per million (a water filter can help you maintain this).
