The Scissortail Rasbora, scientifically known as Rasbora trilineata, is a popular freshwater fish native to the slow-moving rivers and streams of Southeast Asia. This species is known for its striking appearance and active schooling behavior, making it a favorite among aquarists who enjoy vibrant and lively community tanks.

Scissortail Rasboras have a sleek, streamlined body with a shimmering silver base color. Their most distinctive feature is the bold, black, scissor-like marking on the tail, which gives them their common name. This marking is complemented by subtle hues of yellow or green along the body, particularly under proper lighting, adding to their visual appeal. The scissor-like movement of their tails as they swim adds a dynamic element to their appearance.

In captivity, Scissortail Rasboras thrive in spacious, well-planted aquariums that offer plenty of swimming room. These fish are active swimmers and prefer tanks with open areas where they can school together. A well-maintained tank with gentle water flow and a mix of live or artificial plants, as well as driftwood or rocks, will help mimic their natural environment. They appreciate clear, slightly acidic to neutral water, and regular water changes are important to maintain water quality.

As schooling fish, Scissortail Rasboras should be kept in groups to promote their natural social behavior. A group of these rasboras will not only feel more secure but will also display more vibrant colors and energetic movement, creating a mesmerizing effect in the aquarium.

Their diet is straightforward and easy to manage. Scissortail Rasboras are omnivorous and will readily accept a variety of foods, including high-quality flake food, micro pellets, and live or frozen foods such as brine shrimp or daphnia. A varied diet helps ensure their health and keeps their colors bright.

Breeding Scissortail Rasboras in captivity can be achieved with the right conditions. They are egg scatterers, typically spawning among fine-leaved plants or spawning mops. To encourage breeding, it’s best to maintain slightly warmer water and a separate breeding tank. After the eggs are laid, the adults should be removed to prevent them from eating the eggs. The eggs hatch in a few days, and the fry can be fed infusoria or finely crushed flake food until they grow large enough to eat larger foods.

Overall, the Scissortail Rasbora is an excellent choice for both novice and experienced aquarists. Their peaceful nature, striking appearance, and active schooling behavior make them a perfect addition to community tanks, especially those designed to replicate Southeast Asian river environments. With proper care and attention to water quality, they can live long, healthy lives and bring movement and beauty to any aquarium.
