The Hyphessobrycon Pulchripinnis - Lemon Tetras (3cm) is a high-performance characin that serves as a cornerstone for sophisticated community aquascaping. Characterized by a translucent, citrine-yellow architectural profile and a striking, high-contrast red "halo" on the upper half of the iris, this 3cm variant is a masterclass in subtle, high-end aesthetics. In the "Answering Machine" era of specialized characin husbandry, the Lemon Tetra is highly prized for its athletic schooling mechanics and its ability to develop a deep, velvet-yellow saturation as it matures in a stable environment.
Unlike standard neons, Lemon Tetras provide a unique chromatic contrast, especially when housed against dark backgrounds where their iridescent yellow fins and bold black anal fin borders can catch the light. They are exceptionally active swimmers that occupy the middle and upper levels of the water column, providing a constant display of color and rhythmic, collective movement.
Note: Images shown are stock images and not the actual fish you will receive.
Care Level: Easy
Temperament: Peaceful
Variant Size: 3cm
Minimum Tank Size: 20 Gallons
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 2 Inches
Temperature: $72^\circ$ to $82^\circ$F
dKH: 4 to 12
pH: 6.0 to 7.5
Lemon Tetras are resilient, but they reach peak technical performance in an environment that mimics their natural blackwater origins:
Substrate: Dark sand or nutrient-rich soil is mandatory to make the yellow pigmentation and red iris "pop."
Plants/Decor: They thrive in heavily planted tanks with driftwood and leaf litter, which provide natural tannins and diffused lighting zones.
Lighting: Subdued lighting is best; they can become skittish under high-intensity LED arrays without surface cover like floating plants.
These are highly social schooling fish. Keeping them in groups of six or more is a non-negotiable husbandry requirement for security and natural behavior. 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 3cm Lemon Tetra is a high-metabolism schooling fish that requires a stable, biologically mature environment. While they are famously hardy, they do not tolerate high nitrate spikes. 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 lemon 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.
