schooling behaviour. Native to the blackwater tributaries of the Orinoco and upper Amazon basins, this species exhibits pronounced sensitivity to environmental stability and water chemistry, making consistent husbandry essential for long-term health and colour retention.\u003c\/p\u003e\n\u003cp\u003eBody coloration features a continuous neon-blue stripe extending from the snout to the caudal peduncle, underlaid by a saturated red band running the full length of the body. Colour intensity and contrast are directly influenced by water softness, acidity, temperature stability, and low-stress conditions. Behaviour is peaceful and tightly schooling, with synchronized movement observed in well-established groups.\u003c\/p\u003e\n\u003cp\u003eIndividuals supplied are lab-reared and system-acclimated within controlled, closed-system environments, reducing early-life stress and improving adaptability to mature aquaria.
