Danio rerio

Danio rerio, commonly known as the Zebra Danio, is a popular freshwater fish among aquarists due to its hardy nature and distinctive striped pattern. Native to the rivers of South Asia, particularly in India and Bangladesh, Zebra Danios are small, active fish that typically reach about 2 inches in length. Their characteristic blue and silver stripes make them an attractive addition to any aquarium. Zebra Danios are also known for their resilience, making them ideal for beginners and experienced aquarists alike.

Zebra Danios are schooling fish and thrive when kept in groups of at least six. They are incredibly active swimmers, often darting around the tank, which adds dynamic movement to the aquarium. These fish are adaptable to a wide range of water conditions, but they prefer slightly cooler water, around 64-75°F (18-24°C). They are omnivorous and accept a variety of foods, including flake, frozen, and live foods.

In addition to their popularity in home aquariums, Zebra Danios are also significant in scientific research, particularly in genetics and developmental biology, due to their transparent embryos and rapid development. When keeping Zebra Danios in a community tank, it is essential to ensure they are housed with other peaceful species that can tolerate their active nature. Providing plenty of open swimming space along with some plants for cover will create an ideal environment for these lively fish. Overall, Danio rerio is a versatile and engaging species that can bring both beauty and energy to your aquarium.
