Crystal Red Tetra - Hyphessobrycon haraldschultzi Fish Profile & Care Guide
Introduction
Crystal Red Tetras (Hyphessobrycon haraldschultzi) are a captivating species of freshwater fish from the Characidae family, native to South America. What sets them apart is their vibrant red colouration, a feature that has made them a popular choice among aquarists. Their peaceful disposition and adaptability further enhance their appeal, making them an excellent fit for community aquariums. Whether you're a novice or an experienced aquarist, these visually striking and relatively easy to care for Tetras are a versatile addition to any freshwater aquarium.
Crystal Red Tetras are exceptionally peaceful, making them ideal candidates for a well-researched community aquarium. They thrive best when housed with similarly sized species such as other tetras, hatchetfish, pencilfish, Corydoras catfish, plecos, and non-aggressive, small-to-medium-sized Cichlids. It is advisable to avoid housing these Tetras with aggressive or predatory fish and any slow-swimming species that possess long fins. The latter may become targets for fin-nipping. For optimal results, it is recommended that a mixed-sex group of at least 8 to 10 individuals be acquired, and other schooling fish should be included to enhance their sense of security. This approach will reward aquarists with a more natural and visually appealing aquatic display.
Crystal Red Tetras require a well-maintained aquarium closely mimicking their natural habitat to thrive. An ideal tank should have a capacity of at least 90 litres to accommodate a small school, with plenty of swimming space and hiding spots created by plants, driftwood, and rocks. Water conditions must be carefully monitored, maintaining a pH between 5.0 and 7.0 and temperatures varying from 22 to 26 degrees Celsius. A gentle filtration system is required to keep the water clean and well-oxygenated while avoiding strong currents that may stress the fish. Regular partial water changes, approximately 25% weekly, are crucial to maintaining optimal water quality. Additionally, providing a dimly lit environment with subdued lighting and a dark substrate will help highlight the vibrant colours of the tetras and promote their natural behaviour.
Crystal Red Tetras display a distinctive colouration, ranging from pinkish-red to reddish-brown, with a prominent dark spot behind the gill plate. Additionally, their dorsal fin features a dark marking, elegantly framed above by a white blotch and below by a yellowish band, adding to their visual appeal. The anal and pectoral fins of these tetras are delicately edged in white, contributing to their striking appearance. This combination of colours and markings makes them a visually captivating choice for aquarists seeking to enhance the aesthetic of their aquariums.

Sexual Dimorphism
Crystal Red Tetras exhibit subtle sexual dimorphism, which can be discerned primarily by examining the physical characteristics of mature individuals. Generally, females tend to have a slightly fuller and rounder body shape, especially when gravid, compared to their male counterparts, who are typically slimmer and more streamlined. Additionally, males often display more intensely vivid colouration. This enhanced colouration in males likely plays a role in attracting females during the breeding season.

Natural Habitat
Crystal Red Tetras originate from the Rio Araguaia system, a significant tributary of the Rio Tocantins in the lower Amazon basin, spanning central and western Brazil. These Tetras are predominantly found in minor tributaries, backwaters, and oxbow lakes, avoiding the main river channels. The habitats within the Araguaia drainage are characterized by soft, weakly acidic water, with substrates densely covered by fallen leaves and branches, which provide a naturally dim environment. This specific ecosystem caters to their unique ecological requirements and informs the ideal conditions necessary for their care in aquarium settings.
Breeding
Crystal Red Tetras are known as egg scatterers, meaning they do not exhibit parental care post-spawning. During breeding, a suitable environment is crucial; soft, acidic water and a breeding tank set up with fine-leaved plants or spawning mops can encourage spawning behaviour. The female of this species scatters hundreds of tiny, adhesive eggs among the vegetation or substrate, which the male will then fertilize. To enhance the survival rate of eggs, breeders commonly separate the adult fish from the spawning area after the eggs have been laid. This precaution prevents the adults from consuming the eggs, thereby increasing the likelihood of successful hatching. The eggs will usually hatch within 24 to 36 hours, with fry requiring infusoria or finely ground flake foods initially, progressing to larger foods as they grow.
Diet & Feeding
Crystal Red Tetras are omnivorous and have relatively simple feeding requirements, making them an easy addition to a community aquarium. In their natural habitat, they feed on small invertebrates, plant matter, and organic detritus. In captivity, they thrive on a varied diet, including high-quality flake food, micro pellets, and frozen or live foods such as brine shrimp, daphnia, and bloodworms. Providing a diverse diet ensures balanced nutrition and enhances their vibrant colouration. It is advisable to feed them in small amounts multiple times a day to mimic their natural feeding behaviour and prevent overfeeding, which can lead to water quality issues. Regularly offering a mix of plant-based foods will also help maintain their digestive health and overall well-being.
