Scissortail Rasbora (Rasbora trilineata)

Scissortail Rasbora — Rasbora trilineata

Bring effortless motion and shimmering elegance to your community aquarium with the Scissortail Rasbora. Named for its deeply forked, scissor-like tail fin that flashes like a pair of silver shears with every turn, this active schooling fish is a standout centerpiece in any freshwater setup.

Hailing from the slow-moving rivers and flooded forests of Southeast Asia, the Scissortail Rasbora pairs a sleek, silvery body with bold black lateral stripes that run from gill to tail. Under aquarium lighting, their scales catch a subtle iridescent glow, and their signature forked tails create a mesmerizing flicker as the school darts in tight, synchronized formation.

Why aquarists love them:

• Stunning group display:inline: A school of six or more creates a living, shimmering ribbon that transforms the mid-to-upper water column.
• Peaceful community player: Ideal for planted tanks and peaceful communities — they coexist beautifully with tetras, Corydoras, dwarf cichlids, and other rasboras.
• Hardy and adaptable: Tolerates a wide range of water conditions, making them perfect for both newcomers and seasoned hobbyists.
• Generous size: Reaching up to 3.5 inches, they have more visual presence than smaller nano-schoolers without outgrowing standard community tanks.

Quick care snapshot:

• Tank size: 20 gallons minimum (long tanks preferred for active swimmers)
• Temperature: 72–79°F
• pH: 6.0–7.5
• Diet: Omnivore — high-quality flakes, micro-pellets, freeze-dried or frozen treats
