The Hemigrammus Bleheri - Rummynose Tetra (3cm) is a high-performance biological indicator, engineered for rhythmic schooling and precision water quality monitoring in technical freshwater systems. Characterized by a saturated, deep-red cranium, a sleek silver-white body, and a distinctive black-and-white horizontally barred caudal fin, this specimen is a masterclass in aquatic signaling. In the "Answering Machine" era of specialized freshwater husbandry, the Rummynose is prized for its tight schooling discipline and its role as a "canary in the coal mine"—its head color provides real-time feedback on the biological stability of the environment.
Unlike more loosely-shoaling characins, H. bleheri maintains a rigid, high-velocity formation, providing a constant display of synchronized movement through the middle and lower water column.
Note: Images shown are stock images and not the actual fish you will receive.
Visualization Note: Some product imagery utilizes generative AI to provide a high-fidelity representation of a mature specimen’s architectural profile. These are not photos of the specific individual you will receive, as biological variance is a standard in high-end husbandry.
Care Level: Moderate
Temperament: Peaceful
Variant Size: 3cm
Minimum Tank Size: 20 Gallons
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 2 Inches
Temperature: $75^\circ$ to $84^\circ$F
dKH: 2 to 10
pH: 5.5 to 7.0
The Rummynose Tetra requires a stable freshwater environment with high oxygenation and specific structural complexity:
Structural Layout: Significant use of driftwood and dense perimeter planting is mandatory to provide security. The central water column must remain open for high-speed schooling lanes.
Water Quality: This species is exceptionally sensitive to nitrate and ammonia spikes. A mature, biologically stable system is non-negotiable for maintaining the characteristic red cranium.
Lighting: Subdued or "blackwater" style lighting will emphasize the contrast between the red head and the barred tail.
This is an elite schooling species. To maintain social stability and trigger natural schooling mechanics, they must be kept in groups of 10 or more. They are exceptionally peaceful and integrate perfectly with other non-aggressive residents like Discus, Angelfish, Corydoras, and other soft-water specialists. Avoid housing with hyper-aggressive competitors that may disrupt the school's rhythm.
Success with Hemigrammus bleheri hinges on a precision nutritional protocol and water stability. They are active foragers and should be fed twice daily with high-quality flakes or micro-granules. Supplement with frozen daphnia, cyclops, and bloodworms to maintain peak color saturation and metabolic health. Regular 25% weekly water changes using soft, slightly acidic water are the primary success factor for long-term vitality.
We utilize specialized logistics for national Overnight Delivery to ensure livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs to maintain stable temperatures throughout the journey. This protocol is strictly designed to minimize transport stress and ensure a technical transfer from our facility to your tank with zero compromise on health or vitality.
