🐟 Redtail Tinfoil Barb (Barbonymus altus)
Freshwater Barb • Peaceful Schooling • Large Display Fish • Silver Body with Red Fins
📋 The Redtail Tinfoil Barb (Barbonymus altus) is a large, peaceful schooling fish admired for its silver body and vivid red fins. Slightly smaller and more manageable than its close relative the Silver Tinfoil Barb (B. schwanenfeldii), it’s a favorite for aquarists wanting an active, elegant display species.
These fast-swimming barbs thrive in groups of five or more, where they exhibit synchronized motion and dazzling flashes under aquarium lighting. They make excellent community fish when housed with similarly sized, non-aggressive tankmates.
Provide a large, well-filtered aquarium with open space for swimming and minimal obstructions. Their graceful, fluid movements make them a standout centerpiece in any freshwater setup.
