Girardinus metallicus, known as the Metallic Livebearer, is a vibrant and hardy freshwater fish with striking metallic coloration.
Overview
Girardinus metallicus, commonly known as the Metallic Livebearer or Metallic Girardinus, is a striking freshwater fish native to Central America. This species is recognized for its beautiful metallic sheen, which varies in color from gold to silver. Growing up to 4-5 cm in length, it is a hardy and active fish, making it a popular choice for freshwater aquariums.
Tank Requirements
Girardinus metallicus thrives in a well-maintained aquarium with a minimum volume of 50 liters. The water temperature should be kept between 22-28°C, with a pH range of 6.5 to 7.5 and water hardness (GH) between 5-15. A well-filtered tank with regular water changes is essential to maintain water quality. Providing a planted tank with some open swimming space and hiding spots will enhance the fish's well-being.
Feeding and Diet
In the wild, Metallic Livebearers feed on small invertebrates and plant matter. In captivity, they can be fed a varied diet including high-quality flake foods, live or frozen foods such as brine shrimp, daphnia, and finely chopped vegetables. A balanced diet will promote vibrant coloration and overall health. Feed them small amounts 1-2 times a day.
Care and Maintenance
Caring for Girardinus metallicus involves maintaining clean and stable water conditions. Perform regular water changes of 20-30% weekly to prevent the buildup of waste. Monitor water parameters regularly and adjust as needed to keep them within the ideal range. This species is relatively hardy but should still be monitored for any signs of illness or stress.
Compatibility
Girardinus metallicus is generally peaceful and can be kept with other small, non-aggressive fish. Suitable tank mates include other livebearers, small tetras, and peaceful bottom-dwellers. Avoid housing them with larger or aggressive species that might intimidate or harass them. Providing a well-balanced community tank will help ensure their well-being.
Breeding
Breeding Girardinus metallicus in captivity is relatively straightforward. They are livebearers, meaning they give birth to free-swimming fry rather than laying eggs. To encourage breeding, maintain stable water conditions and provide a variety of food options. Pregnant females will carry the fry until they are ready to be born. It is helpful to have a separate breeding tank or provide plenty of hiding spots to protect the young from being eaten by adults.
