Red Wagtail Swordtail (Xiphophorus hellerii)

Red Wagtail Swordtail (Xiphophorus hellerii) is a popular freshwater fish species often kept in aquariums. Here are some details about its care requirements and characteristics:

1. Temperature: Red Wagtail Swordtails prefer a water temperature range of 72-82°F (22-28°C). They are a tropical species, so maintaining a stable temperature within this range is essential for their well-being.

2. Minimum Tank Size: A minimum tank size of 20 gallons is recommended for a small group of Red Wagtail Swordtails. They are active swimmers and appreciate having some space to move around. A larger tank is preferable if you plan to keep a larger group or other fish species with them.

Feeding Habits: Red Wagtail Swordtails are omnivorous and will eat a variety of foods. Their diet should include high-quality flake or pellet foods specially formulated for tropical fish. You can also supplement their diet with live or frozen foods like brine shrimp, daphnia, and bloodworms. Offering a varied diet is important to ensure they receive the necessary nutrients.

Habitat Preference: In the wild, Red Wagtail Swordtails are typically found in slow-moving or still waters of rivers, streams, and canals in Central America. In an aquarium, they appreciate a setup that mimics this natural habitat. Providing live or artificial plants, driftwood, and hiding places is beneficial. They can adapt to various water conditions, but they prefer a well-planted tank with a mix of open swimming spaces.

Water pH Level: The ideal pH level for Red Wagtail Swordtails is in the range of 7.0 to 8.0. They can tolerate a slightly broader pH range but should not be kept in extremely acidic or alkaline water.

Behavior: Red Wagtail Swordtails are generally peaceful and social fish. They are known for their striking colors, with the males being more colorful and having the characteristic sword-like extension of their tail fin. Males can sometimes exhibit aggression towards each other, especially if kept in too small a space or if there is a lack of females. It's recommended to keep a group of females with one male to disperse aggression.

Red Wagtail Swordtails are not true schooling fish, but they do best when kept in small groups. This allows for a more natural and social behavior. Keeping them with other peaceful community fish is also a good idea, as they are not aggressive and are generally compatible with a wide range of tankmates.

Red Wagtail Swordtails are livebearers, meaning they give birth to live fry rather than laying eggs. Breeding is relatively easy in a well-maintained aquarium with the right conditions. You can keep a ratio of one male to multiple females to ensure successful breeding. The fry are usually well-developed and can be raised in a separate tank.

Remember to monitor water parameters, maintain good water quality, and provide a balanced diet to ensure the health and well-being of your Red Wagtail Swordtails. Proper care will help these fish thrive in your aquarium.
