The Hyphessobrycon Rosaceus - Rosy Tetra (2.5cm) is a high-performance characin that offers a sophisticated, deep-bodied architectural profile for the technical community aquarium. Characterized by a translucent salmon-pink body and striking "flag" markings on the dorsal and anal fins—white tips contrasted against bold black—this 2.5cm variant is a masterclass in elegant aquatic aesthetics. In the "Answering Machine" era of specialized characin husbandry, the Rosy Tetra is highly prized for its peaceful schooling mechanics and its ability to add a warm, rhythmic glow to well-maintained planted systems.
Unlike standard slender tetras, Rosy Tetras possess a deeper, more robust profile that creates a significant visual presence within a school. They are exceptionally active swimmers that occupy the middle levels of the water column, providing a constant display of color and calculated collective movement.

Care Level: Easy
Temperament: Peaceful
Variant Size: 2.5cm
Minimum Tank Size: 20 Gallons
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 1.75 Inches
Temperature: 72° to 82°F
dKH: 4 to 12
pH: 6.0 to 7.5
Rosy Tetras reach peak technical performance in an environment that mimics their natural South American riverine origins:
Substrate: Dark sand or nutrient-rich soil is mandatory to make the salmon-pink pigmentation "pop."
Plants/Decor: They thrive in heavily planted tanks with driftwood, which provides natural hiding spots and diffused lighting zones.
Lighting: Subdued or moderate lighting is best; high-intensity arrays should be mitigated with floating vegetation to prevent skittish behavior.
These are highly social schooling fish. Keeping them in groups of six or more is a non-negotiable husbandry requirement for security and natural social display. They are excellent candidates for community tanks, pairing well with other peaceful characins, rasboras, corydoras, and dwarf cichlids. Avoid housing them with large, predatory species that may view them as a food source.
The 2.5cm Rosy Tetra is a high-metabolism schooling fish that requires a stable, biologically mature environment. While they are hardy, they do not tolerate high nitrate spikes or rapid fluctuations in water chemistry. They should be fed a varied diet consisting of high-quality flakes, micro-pellets, and frozen meaty foods—such as daphnia and vitamin-enriched brine shrimp—at least twice daily to maintain peak vitality and their namesake rosy coloration.
We’ve dialed in the logistics for national Overnight Delivery to ensure your livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs, designed to maintain stable temperatures throughout the journey. We handle the technical side of the move so you can focus on the acclimation. Our protocol is built on getting these fish from the facility to your tank with zero compromise on health or vitality.
