Golden Wonder Killifish are generally peaceful and can be kept with other non-aggressive fish of similar size. Some suitable tank mates include other small killifish, rasboras, and tetras. However, it’s essential to keep a tight-fitting lid on the aquarium, as these fish are known for their jumping abilities.
