fredcochui\u003c\/em\u003e), offered by Nero Labs, is a selectively maintained ornamental characin recognized for its compact body form, metallic blue to steel-grey coloration, and high-energy

Native to blackwater and clearwater tributaries of the upper Amazon basin, this species displays strong colour responsiveness to water quality, lighting conditions, and environmental stability.\u003c\/p\u003e\n\u003cp\u003eBody coloration presents as a cool metallic blue with reflective highlights, often intensifying under subdued lighting and low-stress conditions. Fins are typically translucent with subtle dark edging. Behaviour is fast-moving and social, with tight schooling observed when maintained in adequate group sizes. Due to its activity level, this species benefits from open swimming space and structured aquaria.\u003c\/p\u003e\n\u003cp\u003eIndividuals supplied are lab-reared and system-acclimated within controlled, closed-system environments, reducing early-life stress and improving long-term adaptability to established aquaria.
