Table of contents
Introduction
Mini Rosy Tetras (Hyphessobrycon Dorsalis) exemplify a tranquil and adaptable nature, endearing them to numerous aquarium enthusiasts seeking a hassle-free addition to their aquatic collections.
To ensure the well-being of these charming Tetras, it is advisable to maintain them in groups comprising a minimum of six individuals. Such groupings not only promote their overall welfare but also facilitate the formation of a natural-looking shoal, fostering a sense of security among the fish. Moreover, the presence of several male Mini Rosy Tetras may lead to captivating displays of fin flaring, adding to the allure of their communal dynamics.
When selecting compatible tankmates for the Mini Rosy Tetras, favouring smaller and peaceable species, such as smaller Teras, Corydoras Catfish, Hatchetfish, Micro Rasboras, small to medium-sized Barbs, Dwarf Gouramis, and Shrimp, is a prudent approach. However, it is advisable to avoid pairing them with significantly larger or more boisterous species that could potentially cause distress to these delicate tetras.
Designing a planted aquarium featuring darker substrates or creating subdued areas within the tank proves optimal for providing an ideal habitat for the Mini Rosy Tetras. Such environmental conditions not only accentuate the vibrancy of their colours but also contribute to the overall robustness of their health.
The Mini Rosy Tetras possess a gracefully slender physique, distinguished by their non-extended dorsal fins, setting them apart from many other species within this group. Displaying a translucent appearance with gentle light brown hues, their dorsal fins showcase captivating black and white markings, further enhancing their captivating allure.

Natural Habitat
Mini Rosy Tetras are native to the Rio Caures Basin situated in Brazil, South America. These Tetras are typically found in habitats characterized by moderately flowing tannin-stained waters, where the substrate is covered with twigs and leaf litter.
Breeding
To achieve successful breeding and optimize fry yield for Mini Rosy Tetras, the utilization of a dedicated breeding tank is imperative. This specialized tank should ideally be dimly lit and equipped with bundles of fine-leaved plants, such as java moss or spawning mops, providing a suitable substrate for the deposition of eggs by the fish. Alternatively, utilizing a mesh bottom with appropriately sized openings to permit the passage of eggs while preventing adult access can also be considered.
Creating an ideal spawning environment necessitates ensuring the water parameters are soft and acidic. Implementing water filtration through peat and employing RO water can prove advantageous, while a small air-powered sponge filter can provide the gentle current essential for breeding. For successful spawning, it is advisable to maintain a group of approximately half a dozen individuals of each sex.
The group should be adequately conditioned with ample quantities of small live or frozen foods to facilitate uncomplicated spawning. Alternatively, breeding can be conducted in pairs, with females and males prepared separately in distinct tanks. By selecting the most fecund female and the most vibrantly coloured male, they can be transferred to the spawning tank during the evening to initiate spawning the following morning.
Prompt separation of the eggs is imperative since adult Mini Rosy Tetras have a tendency to consume them. The eggs typically hatch within a span of 24 to 36 hours, with the fry attaining free-swimming capabilities approximately five days later.
During the initial days of the fry's life, feeding them with infusoria-type food is recommended until they are ready to consume brine shrimp nauplii or microworms. It is essential to maintain a dimly lit environment in the tank, as the eggs and fry are particularly sensitive to light during their early developmental stages.
Diet & Feeding
Maintaining the dietary requirements of Mini Rosy Tetras within the aquarium setting proves to be a straightforward undertaking, as they are not excessively selective feeders. Nevertheless, prioritizing a nutritionally balanced diet is crucial for promoting their overall health and well-being.
A well-rounded feeding regimen should encompass a combination of high-quality dried foods, including flakes, micropellets, and granules, supplemented by live and frozen offerings such as bloodworms, white mosquito larvae, daphnia, and vitamin-enriched brine shrimp.
By incorporating this diverse array of food sources, caretakers can ensure that their Rosy Tetras receive the essential nutrients indispensable for fostering optimal growth and vitality.
