The Japan Double Sword Endler is a small, vibrant livebearer fish known for its unique double tail-sword extensions and hardy nature, making it ideal for both beginner and experienced aquarists. They thrive in groups in a well-planted aquarium of at least 10 gallons with stable, clean water. Endlers prefer slightly alkaline conditions, moderate temperatures, and a varied diet of high-quality flakes, micro-pellets, and live or frozen foods like brine shrimp and daphnia. As peaceful fish, they do well in community tanks with other small, non-aggressive species but should not be kept with fin-nippers. Since they breed readily, keeping more females than males helps reduce stress and overbreeding.
