Red Line Tetra - Hyphessobrycon amapaensis : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Red Line Tetra (Hyphessobrycon amapaensis) is a striking and dynamic fish that will add a touch of beauty to any aquarium. These Tetras are active and peaceful, and when kept in a group, they create a stunning display of movement and colour that will capture the attention of any observer. Overall, the Red Line Tetra is an excellent choice for any aquarist looking to add a touch of beauty and elegance to their aquarium.
The proper husbandry of Red Line Tetras necessitates their presence in sufficiently sized congregations, with no less than 6 individuals being the minimum recommendation. Ideally, a grouping of 10 or more individuals is advised for optimal results. This approach serves dual purposes: it instils a heightened sense of security among the fish and concurrently yields a more pronounced and authentic representation of their inherent shoaling behaviour.
When it comes to tankmates, these Tetras are compatible with a wide range of small and peaceful species, making them a versatile addition to any community tank. However, it's important to keep in mind that they can be easily frightened, so it's best to avoid housing them with much larger, boisterous species.
Red Line Tetras are particularly well-suited for established softwater aquatic environments. The aquarium setting should be thoughtfully outfitted with an abundance of driftwood strategically positioned to establish ample shaded zones. The gradual infusion of tannins from the driftwood serves a dual purpose: contributing to the gradual acidification of the water while imbuing it with an authentic, translucent amber hue reminiscent of fine tea. To further bolster the acidification process, the integration of peat filtration is also a beneficial consideration.
While the presence of aquatic vegetation might not be prolific within the natural habitats of this species, a moderate degree of plant incorporation is advisable. This botanical arrangement not only imparts a sense of security to the fish but also enhances the overall aesthetics of the environment. Regarding lighting, a subdued intensity is recommended, and the interplay of tannins and floating flora can aid in diffusing excessive luminosity. Opting for a darker substrate and background selection is prudent, as it will effectively accentuate the vivid and intricate colouration of the Red Line Tetras.
Their sleek and slender body has a silvery iridescence with a striking thick red line that runs from the gill plate to the caudal peduncle. The thin white band underneath the red line is followed by a black band, creating a stunning contrast against their silver body. Their fins are generally colourless, with a subtle hint of yellow that completes their stunning appearance.

Sexual Dimorphism
Distinguishing between male and female Red Line Tetras is a challenging task, as there are few observable differences between the sexes. Nevertheless, one noticeable distinction is the larger size and deeper body of sexually mature females when compared to males. By carefully observing these subtle differences, aquarium enthusiasts can accurately identify the sex of their Red Line Tetras and tailor their care accordingly.

Natural Habitat
The Red Line Tetra is a fascinating fish that inhabits the Rio Maraca and Rio Preto drainages in Amapa state, Northeastern Brazil. This species can be found in small streams and creeks that flow through the vast savanna grasslands of the region, where they thrive in light brown, crystal-clear waters. The substrate of their natural habitat is composed of gravel and sand, with little to no submerged or riparian vegetation. The unique environment that the Red Line Tetra calls home has contributed to its distinctive appearance and behaviour.
Breeding
The Red Line Tetra is a prolific species that will readily spawn in ideal conditions, and it is not uncommon for small numbers of fry to appear in a well-established aquarium without intervention. However, for those seeking to maximize yield, a more controlled approach is necessary. Conditioning the adult group together is a necessary first step, but it is also essential to set up a smaller aquarium filled with mature water. This environment should be dimly lit and feature a bottom covered with mesh or plastic grass matting or, alternatively, a layer of fine-leaved plants or glass marbles. Spawning mops can also yield excellent results.
Water conditions should be slightly acidic to neutral, with a temperature towards the higher end of the acceptable range. An air stone or air-powered sponge filter can provide the necessary water movement and oxygenation. Once the adult fish are well-conditioned, a single pair or group containing several females and one or two males can be introduced to each tank and left in place until eggs are discovered, typically the following morning.
Feeding the resulting fry initially with infusoria or Paramecium or an exclusive dry food of sufficiently small size is crucial. As the fry grows, they can be introduced to foods such as microworm and Artemia nauplii to ensure healthy development. With proper care and attention, hobbyists can enjoy a flourishing population of Red Line Tetras in their aquarium.
Diet & Feeding
Red Line Tetras should be provided with a diverse diet consisting of high-quality foods such as flakes and micropellets. In addition, it is recommended to supplement their diet with small frozen foods such as bloodworms, white mosquito larvae, vitamin-enriched brine shrimp, Moina, and daphnia. A well-balanced and varied diet will help ensure the optimal health and vibrant colouration of these Tetras.
