The Eurasian Minnow, scientifically known as Phoxinus phoxinus, is a small and robust species of freshwater fish native to the rivers, streams, and lakes of Europe and parts of Asia. This species is appreciated by aquarists for its hardiness, adaptability, and active behavior, making it a good addition to well-maintained community aquariums and coldwater setups.

Eurasian Minnows are characterized by their slender, elongated bodies and attractive coloration. Their bodies typically display a silvery base color with a series of dark spots or stripes running along their sides. During the breeding season, males become more colorful, with vibrant hues of red or orange on their fins and bellies, making them particularly eye-catching. Their fins are generally clear or slightly tinted, complementing their elegant appearance.

In captivity, Eurasian Minnows thrive in aquariums that closely mimic their natural habitat. A tank setup should include a soft, sandy or fine gravel substrate and plenty of live plants, such as Java moss, Anubias, and Vallisneria, which provide cover and create a comfortable environment. Adding rocks, driftwood, and other decorations can enhance the natural look of the tank and provide additional hiding spots.

Water conditions should be cool to temperate, with slightly acidic to neutral pH levels and moderate hardness. Maintaining stable water parameters through regular water changes and efficient filtration is crucial for the health and well-being of Eurasian Minnows. They are relatively hardy fish but do best in clean, well-oxygenated water with a gentle to moderate current.

Eurasian Minnows are social fish that should be kept in groups of at least six or more to promote their well-being and natural schooling behavior. Keeping them in a school not only reduces stress but also enhances their active swimming patterns. They are peaceful and can be housed with other similarly sized, non-aggressive fish, making them ideal for community tanks.

Their diet should be varied to ensure they receive all necessary nutrients. Eurasian Minnows are omnivorous and will readily accept high-quality flake foods, small pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. Providing a mix of these foods will help maintain their health, vibrant colors, and energetic behavior.

Breeding Eurasian Minnows in captivity can be relatively straightforward under the right conditions. They are egg scatterers, typically laying their eggs on gravel or plants. To encourage breeding, maintain optimal water conditions with cool, clean water and provide plenty of hiding spots and spawning substrates. Once spawning occurs, it is advisable to remove the adults from the breeding tank to prevent them from eating the eggs. The eggs usually hatch within a few days, and the fry can be fed with infusoria or finely crushed flake food until they are large enough to accept standard fare.

Overall, the Eurasian Minnow is an excellent choice for aquarists looking for a hardy, peaceful, and active species. Their attractive appearance, gentle nature, and ease of care make them a delightful addition to any well-maintained aquarium. With proper care, they can thrive and bring a touch of lively activity and natural beauty to your aquatic setup.
