A popular variation of this species, Kohaku Swordtails belong to the Xiphophorus genus and are native to Central America. The most common species kept in aquariums is the Xiphophorus hellerii. Swordtails are known for their distinct elongated lower fin, resembling a sword.

Swordtails have a streamlined body shape with vibrant colors. Males have a sword-like extension on their lower caudal fin, while females have a more rounded fin. They come in various color variations, including red, orange, yellow, and black.

Swordtails can grow up to 4 to 6 inches (10 to 15 cm) in length, with males usually being slightly smaller than females. Behavior: Swordtails are generally peaceful and active fish, making them suitable for community aquariums. They are known to be lively swimmers and can often be seen exploring all levels of the tank.

Swordtails prefer a slightly alkaline water condition with a pH range between 7.0 and 8.3. The temperature should be maintained between 72°F to 82°F (22°C to 28°C). Providing a well-filtered aquarium and regular water changes are essential for their well-being.

Swordtails are omnivorous and will eat a variety of foods. They can be fed high-quality flake or pellet food designed for tropical fish. It's recommended to supplement their diet with occasional live or frozen foods like brine shrimp, bloodworms, or daphnia.

Swordtails appreciate a well-planted aquarium with open swimming areas. A tank size of at least 20 gallons or larger is recommended for a small group of Swordtails. Providing hiding spots, rocks, and driftwood can create a more natural and stimulating environment.

Swordtails are livebearers, similar to Mollies. Female Swordtails can store sperm from a single mating and produce multiple broods over time. They give birth to live fry, and the gestation period is typically around 4 to 6 weeks.

Remember to research the specific care requirements of the Swordtail species you plan to keep, as different variations may have slightly different needs. It's also essential to monitor water parameters and ensure a balanced diet to keep your Swordtails healthy and thriving.
