The Longfin Zebra Danio, scientifically known as *Danio rerio*, is a beautiful and hardy freshwater fish, popular among aquarists for its striking appearance and active behavior. This variety is a long-finned version of the standard Zebra Danio, featuring elegant, flowing fins that enhance its graceful movement in the water. Native to South Asia, these fish are adaptable and well-suited for both beginners and experienced hobbyists.

Longfin Zebra Danios have slender, streamlined bodies adorned with distinct horizontal stripes that run from head to tail. These stripes are usually blue or black and contrast with a silvery or golden background. The long, delicate fins of this variety add an extra touch of elegance, making them a visually appealing addition to any aquarium. Their energetic swimming behavior and playful nature bring life to the tank.

In captivity, they thrive in well-maintained aquariums that provide ample swimming space. These fish are highly active and require open areas to move freely. Adding plants, driftwood, and rocks can create hiding spots and help mimic their natural habitat. They prefer clean, well-oxygenated water, and maintaining water quality through regular changes and effective filtration is essential for their health. While they are highly adaptable, gentle water flow and stable conditions contribute to their well-being.

Longfin Zebra Danios are social fish that should be kept in groups. They are happiest in schools of at least six or more, which reduces stress and encourages natural schooling behavior. Their peaceful nature makes them excellent community tank members, compatible with other small, non-aggressive species like tetras, rasboras, and Corydoras.

These fish are omnivorous and easy to feed. They will readily accept high-quality flake foods, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. A varied diet helps maintain their vibrant coloration and energy levels, ensuring they remain active and healthy.

Breeding Longfin Zebra Danios is relatively straightforward. They are egg scatterers, laying their eggs among fine-leaved plants or spawning mops. A separate breeding tank is recommended to protect the eggs and fry, as adults may consume the eggs. Once the eggs hatch, which usually occurs within a few days, the fry can be fed infusoria or finely crushed flake food until they grow large enough to eat standard foods.

The Longfin Zebra Danio is an excellent choice for aquarists looking for a lively and visually appealing species. Their flowing fins, bright colors, and sociable nature make them a joy to keep and observe. With proper care and a suitable environment, they thrive and bring dynamic energy and elegance to any freshwater aquarium.
