Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Longfin Rosy Barbs are social and active fish that enjoy swimming in schools. They are generally peaceful but may exhibit some fin-nipping behaviour, especially towards fish with long fins. Keeping them in a group of at least 6 individuals can help disperse any aggression within the school. They are best kept with other peaceful community fish that can tolerate their active nature.
Tank planning
Maintaining good water quality is essential for the health of Longfin Rosy Barbs. They prefer well-oxygenated water with moderate water flow. Regular water changes and filtration are important to keep their environment clean and stable. Provide ample hiding places and plants for them to explore and feel secure. Keep an eye on their fins to ensure they are not being damaged by tank mates.
