Chocolate Neon Tetra - Hyphessobrycon vilmae : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Chocolate Neon Tetra (Hyphessobrycon vilmae), a relatively uncommon species within the Characidae family, offers a fascinating addition to freshwater aquatic environments. Originating from the waterways of South America, this species is noted for its striking colouration and animated behaviour, making it a fitting choice for any aquarium setting due to its tranquil yet spirited disposition.
For optimal health and social interaction, it is recommended to house Chocolate Neon Tetras with non-predatory, similarly sized fish. Grouping these Tetras in numbers of eight or more is advisable to create an impressive shoaling effect, enhancing their sense of security and preventing stress-related colour loss. Suitable tankmates include Tetras, Hatchetfish, Pencilfish, Corydoras Catfish, and small to medium-sized Cichlids. Avoiding larger, more aggressive species is crucial to safeguard the well-being of these delicate Tetras.
The ideal habitat for Chocolate Neon Tetras includes a densely planted aquarium with river sand substrate and driftwood branches or roots. While lighting is of secondary importance, providing ample space for unhindered swimming is essential due to their active nature. Additionally, a gentle surface current is beneficial for these fish.
The Chocolate Neon Tetra is characterized by a unique appearance. Their body exhibits a beige-silvery base with a vibrant, fluorescent reddish-orange brown stripe extending from behind the gill cover to the tail base. A black bar, fading downwards, runs parallel to this fluorescent stripe. The belly region is typically lighter in colour, and the upper portion of the eye and the top of the head display a striking coppery tone. Often appearing golden, this colouration in the Chocolate Neon Tetra is attributed to a benign skinworm infection rather than genetic factors.

Sexual Dimorphism
Identifying the gender of Chocolate Neon Tetras is a relatively simple process. Male Chocolate Neon Tetras are distinguishable by their more vivid colouration and the presence of white tips on their fins, features that are absent in females.

Natural Habitat
Chocolate Neon Tetras are native to the upper regions of the Tapajós River Basin, located in Brazil, South America. These fish are commonly found in the smaller tributaries, streams, floodplains, and sandbars within this area. The Tapajós River is characterized as a clear-water river, distinguished by its elevated mineral content and enhanced water clarity.
Breeding
Breeding Chocolate Neon Tetras presents an engaging endeavour, particularly when water conditions are meticulously managed. Initially, prepare a breeding pair with nourishing live foods such as mosquito larvae or brine shrimp, selecting the most vigorous female and the healthiest, most vibrant male.
For successful breeding, a dedicated breeding aquarium is essential. This tank should contain soft, acidic water, a dark substrate, subdued lighting, and a temperature slightly elevated above the norm. Abundant fine-leaved plants are crucial as a spawning substrate, and floating plants can be utilized to further dim the lighting.
Spawning usually occurs in the early hours. The female lays several hundred adhesive eggs on the plants and substrate. Post-spawning, it is critical to promptly remove the adult fish to prevent them from consuming the eggs and hatchlings. The eggs will incubate for approximately 22 to 26 hours, with the fry becoming mobile within three to four days.
Rearing the fry is relatively straightforward. They can be fed with specially formulated commercial foods, finely ground flake foods, or newly hatched brine shrimp. It is important to segregate young Chocolate Neon Tetras until they are sufficiently grown to avoid predation by adult fish. Once they reach an adequate size, they can be reintegrated into the main aquarium.
Diet & Feeding
For optimal health and colouration in Chocolate Neon Tetras, it is advisable to provide a diverse diet that fulfils their nutritional requirements. This diet should consist of premium flakes and granules, complemented by live and frozen foods, including mosquito larvae, daphnia, Moina, and brine shrimp. To adequately meet their nutritional needs, it is important to feed these Tetras several times daily, ensuring the portion size is such that they can consume it entirely within a timeframe of three minutes or less.
