Red Eye Red Line Tetra - Hemigrammus rubrostriatus : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Red Eye Red Line Tetra (Hemmigrammus rubrostriatus), scientifically recognized as a distinct species in 2015, represents a novel addition to the Tetra family and remains a rarity within the aquarium trade. This species exhibits a physical resemblance to the Glowlight Tetra, albeit at a notably larger scale, marking it as a distinctive and appealing choice for collectors and enthusiasts seeking uncommon specimens. Red Eye Red Line Tetras are a freshwater fish that is esteemed among aquarists for their vibrant colouration and dynamic presence within a community aquarium.
The Red Eye Red Line Tetra is characterized by its lively demeanour, frequently traversing the breadth of the aquarium. As a gregarious species, it is imperative to house them in shoals of no fewer than six to eight individuals, a practice that mitigates stress and fosters their inherent social behaviour. These Tetras are inherently docile and compatible with other small to medium-sized, non-predatory aquatic species such as other Tetras, Rasboras, Dwarf Gouramis, and Dwarf Cichlids. However, they should not be housed with larger, aggressive fish that may intimidate or harm them.
An aquascape rich in aquatic flora, including floating plants coupled with ample unobstructed areas for swimming, is recommended. Incorporating elements such as driftwood and rock formations not only provides essential refuge but also mirrors the complexity of their native ecosystem. Subdued lighting is advised to not only accentuate the Tetras’ vibrant hues but also to create a tranquil environment. Rigorous adherence to a maintenance regimen, including weekly water changes of 20 to 25%, is crucial for sustaining optimal water conditions and facilitating efficient waste management. Proper filtration is also essential to maintain a gentle flow of water, simulating their natural habitat conditions.
Red Stripe Tetras boast a dazzling iridescent gold body complemented by a conspicuous red stripe that extends from the operculum along the body to the dorsal region of the caudal peduncle, continuing to the caudal fin rays. Notable is the species’ caudal spot, an elongated, brightly edged mark positioned asymmetrically on the lower portion of the caudal peduncle and the caudal fin base, occasionally reaching the extremities of the fin rays.

Sexual Dimorphism
Sexual dimorphism in Red Eye Red Line Tetras, although subtle, can be discerned with careful observation. Males typically exhibit a more vibrant hue and a somewhat slimmer body profile when compared to their female counterparts. In contrast, females often possess a more rounded abdominal region, particularly when gravid, displaying a slightly more subdued colouration.

Natural Habitat
The Red Eye Red Line Tetra, a species only recently delineated, presently has a limited body of knowledge concerning its native ecological conditions. Nonetheless, it is established that this Tetra species is indigenous to Colombia, South America. Further research is required to fully understand the specific environmental dynamics of their habitat, which will, in turn, enhance our ability to replicate these conditions in captive settings for the well-being of the species in aquaria.
Breeding
Red Eye Red Line Tetras, a species known for egg scattering, present a relatively straightforward reproduction process. For optimal breeding conditions, it is recommended to establish a diminutive, flora-rich aquaculture environment with soft, mildly acidic water, with the temperature adjusted towards the upper spectrum of their preferred range.
The onset of spawning is typically induced by the morning sunlight illuminating the tank, resulting in the dispersion of eggs throughout the enclosure. Post-spawning, it is imperative to promptly remove the adult tetras to prevent predation of the progeny. The eggs are expected to incubate successfully within a 24-hour period.
Due to the diminutive size of the newly hatched fry, they are incapable of ingesting the same diet as adult tetras. It is thus advised to provide them with microscopic nourishment such as infusoria until they mature sufficiently to tackle larger fare. Additionally, the fry exhibit photophobia; hence, a gradual acclimation to standard lighting conditions is crucial to their development.
By the time they reach 8 to 12 weeks of age, the juveniles should begin to manifest the distinctive chromatic patterns characteristic of mature Red Eye Red Line Tetras.
Diet & Feeding
Red Eye Red Line Tetras exhibits omnivorous feeding habits, integrating both plant-based and animal-derived nutrients into its diet. In their natural habitat, these fish are accustomed to a diverse array of food sources, including small invertebrates, crustaceans, and various plant matter. For the Red Eye Red Line Tetra in captivity, a well-balanced diet is critical for maintaining optimal health and colouration. Their nutritional regimen should include high-quality flake foods as a staple, which provides a comprehensive range of essential nutrients.
To ensure a rounded diet, it is recommended to supplement with live or frozen foods such as brine shrimp, daphnia, and bloodworms. These not only furnish the tetras with protein but also encourage natural foraging behaviours. Vegetation is a non-negotiable component of their diet, and offerings such as boiled vegetables or spirulina flakes are beneficial. These additions supply necessary vitamins and minerals, aiding in digestion and contributing to overall vitality.
When feeding Red Eye Red Line Tetra, adherence to a feeding schedule that mimics their natural eating patterns is advisable. Small, measured feedings twice or thrice a day are preferred over a single large feeding, as this mitigates overfeeding and aligns with their instinctual grazing habits.
