Redtail Goodeid
The Redtail Goodeid, scientifically known as Xenotoca eiseni, is a striking and robust freshwater fish species that is highly valued by aquarists for its vivid coloration, hardy nature, and interesting behavior. Native to the rivers, streams, and lakes of central Mexico, particularly in the states of Jalisco and Michoacán, this livebearing fish adds a unique and dynamic presence to a variety of aquarium setups.
Physically, the Redtail Goodeid is most notable for its vibrant tail, which ranges from bright orange to deep red, contrasting beautifully with its silvery or bluish body. Males typically exhibit more intense coloration than females, particularly on the caudal fin and the lower half of the body, where a golden or yellowish tint may also be present. Females are generally larger and more subdued in color, with a fuller body shape. Mature specimens typically reach lengths of around 2.5 to 3 inches (6 to 7.5 centimeters), making them well-suited for medium to large aquariums.
In aquariums, Redtail Goodeids thrive in well-maintained tanks with plenty of swimming space and moderate water flow. They appreciate a setup that includes both open areas for swimming and densely planted sections for hiding and foraging. These fish are relatively active and can be somewhat territorial, especially males, so providing ample space and visual barriers like plants, rocks, and driftwood is essential to reduce aggression and stress.
Water parameters for Redtail Goodeids should closely mimic their natural habitat. They prefer slightly alkaline to neutral water with a pH range of 7.0 to 8.0 and temperatures between 68 to 75°F (20 to 24°C). While they can tolerate a range of water conditions, regular water changes and good filtration are essential to maintaining their health and preventing the buildup of toxins.
Feeding Redtail Goodeids is straightforward, as they are omnivorous and have a hearty appetite. They will readily consume high-quality flakes, pellets, and granules, as well as live or frozen foods such as bloodworms, brine shrimp, and daphnia. They also enjoy vegetable matter, so offering blanched spinach, zucchini, or spirulina-based foods can provide essential nutrients and promote overall health.
Breeding Redtail Goodeids in captivity is relatively easy, as they are livebearers, meaning the females give birth to fully-formed, free-swimming fry. To encourage breeding, provide a well-planted tank with plenty of cover for the fry to hide from potential predation by adults. Female Redtail Goodeids can give birth to a brood of 10 to 30 fry every 6 to 8 weeks, depending on the conditions. The fry are relatively large and can be fed on finely crushed flakes, baby brine shrimp, or specialized fry food.
Overall, the Redtail Goodeid (*Xenotoca eiseni*) is a captivating and hardy addition to freshwater aquariums, prized for its vivid coloration, ease of care, and interesting behavior. With proper care and attention to their specific requirements, these robust livebearers can thrive and bring a dynamic splash of color and activity to aquarists of all levels of experience, enhancing the beauty and diversity of any aquatic environment.
