Neon Tetra - Longfin - Paracheirodon innesi var. "Blue Diamond Longfin" : Complete Fish Profile & Care Guide
Table of contents
Introduction
Known for its captivating allure, the Longfin Neon Tetra (Paracheirodon innesi) has emerged as an influential entity within the aquarium hobbyist sector. Its dazzling iridescent blue and red stripes, which glow vibrantly under suitable lighting, have thrust this species into considerable popularity among aquatic enthusiasts. The hardy nature and cost-effectiveness of the Longfin Neon Tetra, particularly appealing to those exploring aquarists for the first time, further elevates its appeal.
The Longfin Neon Tetra is a sociable species that flourishes in groups of six or more. Observing these vibrant creatures in larger assemblies offers a glimpse into a broad spectrum of their innate behaviours. The enchanting sight of a substantial group, each fish reflecting light off its colourful stripes, is genuinely fascinating. It is, however, inadvisable to keep Longfin Neon Tetras in solitude, as this may lead to stress, frailty, and an increased susceptibility to disease.
Selecting compatible tank mates for Longfin Neon Tetras is critical and should involve integrating non-aggressive species of similar sizes. Pairing them with other Tetra species can yield a diverse and colourful community aquarium. Yet, they can also coexist peacefully with a variety of other fish species. It's important to exercise caution when introducing larger, more aggressive fish that may intimidate or prey on them.
Within a community aquarium setting, Longfin Neon Tetras typically inhabit the middle to lower strata, actively exploring their surroundings. They've been observed to cluster together with Cardinal Tetras, their close relatives. Maintaining a group of Longfin Neon Tetras not only enhances the aesthetic appeal of the aquarium but also fosters a more balanced and gratifying environment for these remarkable fish.
One key to fully savouring the beauty of the Longfin Neon Tetra lies in replicating an environment similar to its native Amazonian habitat within the aquarium. Incorporating dense aquatic planting provides shelter and a sense of security, reflecting the lush vegetation of their natural environments. Adding driftwood roots and branches creates a naturalistic backdrop against which these radiant fish can shine. Integrating dried leaf litter into the substrate can lend a more authentic look and provide extra hiding spots.
In terms of lighting, a somewhat subdued atmosphere best replicates the dappled sunlight of their natural habitat. This doesn't preclude the inclusion of hardy aquatic plants, which can thrive under such conditions. Floating plants can further enhance the aquarium's coverage, contributing to a more immersive environment for the Longfin Neon Tetras.

Sexual Dimorphism
Discerning the sex of Longfin Neon Tetras can present a considerable challenge, primarily due to the absence of pronounced sexual dimorphism in this species. However, certain subtle differences may assist in distinguishing between male and female specimens.
Typically, mature female Longfin Neon Tetras are larger and exhibit a more robust and rounded abdomen. Thus, these subtle physical characteristics can aid in determining the sexes within this enthralling species.

Natural Habitat
The Longfin Neon Tetra is not naturally found in the wild. This uniquely captivating species signifies an exclusive colour morph bred diligently in controlled environments. However, its precursor, the original Neon tetra, hails from tropical regions of Northern South America, with its origins traced back to Western Brazil, Southeastern Colombia, and Eastern Peru. The wild populations of this species are usually located in the tributaries of the Amazon Rivers Tiger, Yarapa, and Napo.
In their indigenous habitats, Longfin Neon Tetras predominantly inhabit both blackwater and clearwater streams. They exhibit a preference for soft, acidic water conditions, replete with dense vegetation and intricate root systems. These serene environments, characterised by lush foliage and placid, transparent waters, furnish the ideal conditions for these spectacular fish to flourish.
While emulating this optimal environment for Longfin Neon Tetras within your home aquarium may entail a modest degree of effort, the rewards are undeniably considerable. Their radiant colours and dynamic behaviours make Longfin Neon Tetras a precious asset to any aquascaping endeavour.
Breeding
Breeding Longfin Neon Tetras presents both an intriguing challenge and a fulfilling endeavour for the dedicated aquarium hobbyist. This process necessitates meticulous attention to water conditions and the development of a bespoke breeding environment.
To initiate the process, a dedicated breeding tank should be established. This environment should feature subdued lighting, efficient filtration, and an abundance of live plants. Elevating the water temperature slightly above the standard can incite the spawning process. Prior to spawning, it is advisable to enrich the tetras' diet with live foods.
When Longfin Neon Tetras attain breeding maturity, the male will clasp the female, who will subsequently release approximately 100 somewhat sticky and transparent eggs. These eggs will affix themselves to the surrounding flora. Following spawning, it's prudent to relocate the parent tetras to mitigate the risk of egg consumption.
Lighting levels should be kept minimal, as both the eggs and ensuing fry are photosensitive. Within a 24-hour span, the eggs will hatch into minuscule fry, subsisting off their yolk sac for a few days. Within three to four days, the fry will transition to free-swimming, and you can commence feeding them with suitable nourishment.
While the breeding of Longfin Neon Tetras necessitates scrupulous care and precision, the exhilarating thrill of witnessing the emergence of new life within your aquarium yields an immensely gratifying experience.
Diet & Feeding
Maintaining dietary diversity is fundamental to the well-being of Longfin Neon Tetras. Fortunately, these fish exhibit an accommodating palate. It's advised to supply them with high-quality flakes and granules as their primary nourishment, supplemented with live and frozen foods, such as bloodworms, brine shrimp, and daphnia, to avert potential nutritional shortfalls.
In addition to these, micro-pellet food can constitute a beneficial supplement to their diet. Consider choosing tropical sinking pellets fortified with natural colour enhancers, as these contribute to accentuating the vibrant hues of the Longfin Neon Tetras. These assorted dietary provisions play a pivotal role in boosting their overall health and vitality.
