The Loreto Tetra (Hyphessobrycon loretoensis) is a captivating and peaceful schooling fish, making it an exquisite addition to any well-maintained community aquarium. Hailing from the pristine blackwater tributaries of the Amazon basin, particularly the Loreto region of Peru, this species embodies the subtle beauty characteristic of South American tetras. Growing to a modest size of about 1.5 to 2 inches (4-5 cm), Loreto Tetras feature a sleek, torpedo-shaped body adorned with a distinctive horizontal stripe that can range from iridescent gold to a vibrant reddish-orange, often complemented by hints of red in their fins and a subtle, almost pearlescent sheen across their flanks. Their elegant appearance is further enhanced when housed in optimal conditions. To thrive, Loreto Tetras require an environment that mimics their natural habitat. A minimum tank size of 10-20 gallons is recommended for a school of at least six individuals, as these fish are much more confident and display their best colors in larger groups. They prefer soft, acidic water with a pH between 5.5 and 7.0, and a temperature range of 72-78°F (22-26°C). A heavily planted aquarium with plenty of natural decor, such as driftwood and leaf litter (e.g., Indian almond leaves), will provide essential hiding spots and help maintain the desired water parameters, often creating a desirable blackwater effect that truly brings out their hues. Darker substrates can also intensify their coloration. Gentle filtration is key, as strong currents can stress these fish. Loreto Tetras are omnivores and will readily accept a varied diet. High-quality flake or micro-pellet foods should be supplemented with frozen or live offerings like bloodworms, brine shrimp, and daphnia to ensure robust health and vibrant colors. Their peaceful demeanor makes them ideal tankmates for other small, non-aggressive species, including other tetras, rasboras, dwarf cichlids, Corydoras catfish, and Otocinclus catfish. Avoid housing them with larger, boisterous, or fin-nipping fish. With proper care and attention to their environmental needs, the Loreto Tetra will bring a dynamic and shimmering elegance to the dedicated aquarist's collection.
