Table of contents
Introduction
Famed for its enticing charm, the Longfin Diamond Neon Tetra (Paracheirodon innesi) has emerged as a significant player in the aquarium cultivation world. Its brilliant iridescent blue and red stripes, which shine vividly under optimal lighting, have propelled this species to substantial popularity within the aquatic hobbyist community. Further enhancing the appeal of the Longfin Diamond Neon Tetra are its hardy nature and cost-effectiveness, particularly for those venturing into aquarists for the first time.
The Longfin Diamond Neon Tetra is a sociable species that thrives in groups of at least six. Observing larger gatherings of these vibrant creatures offers insight into a wide range of their natural behaviours. The entrancing sight of a large group, with each fish's blue and red stripes reflecting light, is genuinely captivating. However, it is ill-advised to keep Longfin Diamond Neon Tetras in isolation, as this can lead to stress, weakness, and a heightened susceptibility to disease.
Choosing compatible tank mates for Longfin Diamond Neon Tetras is crucial and should involve incorporating non-aggressive species of similar sizes. While pairing them with other Tetra species can result in a diverse and colourful community aquarium, they can also peacefully cohabitate with a variety of different fish species. However, caution should be exercised against larger, more aggressive fish that might bully or prey on them.
In a community aquarium setting, Longfin Diamond Neon Tetras typically occupy the middle to lower levels, enthusiastically exploring their surroundings. They have been observed to group together with Cardinal Tetras, their close kin. Maintaining a group of Longfin Diamond Neon Tetras not only amplifies the visual appeal of the aquarium but also encourages a more balanced and satisfying environment for these remarkable fish.
A key to fully appreciating the beauty of the Longfin Diamond Neon Tetra is recreating an environment similar to its native Amazonian habitat within the aquarium. Implementing dense aquatic planting provides shelter and a sense of security, mirroring the lush vegetation of their natural environs. Driftwood roots and branches add to this ambience, creating a naturalistic backdrop against which these radiant fish stand out. The addition of dried leaf litter to the substrate can give a more genuine appearance and provide extra hiding places.
In terms of lighting, a somewhat dimmer atmosphere best mirrors the dappled sunlight filtering through their natural habitat. This doesn't prevent the inclusion of hardy aquatic plants, which can flourish under such conditions. Floating plants can further enhance the aquarium's coverage, contributing to a more immersive environment for the Longfin Diamond Neon Tetras.

Natural Habitat
The Longfin Diamond Neon Tetra does not naturally occur in the wild. This uniquely enchanting species represents an exclusive colour morph bred meticulously in controlled environments. However, the original Neon tetra is indigenous to the tropical regions of Northern South America, with its roots traced back to Western Brazil, Southeastern Colombia, and Eastern Peru. Wild populations of this species are typically found in the tributaries of the Amazon Rivers Tiger, Yarapa, and Napo.
In their native habitats, Longfin Diamond Neon Tetras frequent both blackwater and clearwater streams. They show a preference for soft, acidic water environments filled with dense vegetation and complex root systems. These tranquil environments, characterized by abundant foliage and serene, clear waters, provide the ideal conditions for these spectacular fish to thrive.
Recreating this optimal environment for Longfin Diamond Neon Tetras within your home aquarium may require a modest level of effort, yet the rewards are unquestionably considerable. Their radiant colours and dynamic behaviours make Longfin Diamond Neon Tetras a valuable addition to any aquascaping project.
Breeding
Breeding Longfin Diamond Neon Tetras represents both a challenging and rewarding venture for the dedicated aquarist. This task requires careful attention to water conditions and the creation of a specialized breeding environment. To begin the process, you should set up a breeding tank. This should include subdued lighting, efficient filtration, and a plethora of live plants. Raising the water temperature a few degrees above the usual can stimulate the spawning process. Before spawning, the tetras should be fed with live foods.
When Longfin Diamond Neon Tetras reach breeding readiness, the male will embrace the female, and she will release approximately 100 slightly sticky and transparent eggs. These eggs will then attach to the surrounding plants. After spawning, it's wise to move the parent tetras to avoid the risk of them eating the eggs. Lighting levels should remain minimal as the eggs and subsequent fry are sensitive to light. Within 24 hours, the eggs will hatch into tiny fry, which will live off their yolk sac for a few days. Within three to four days, the fry will become free-swimming, and you can start feeding them with appropriate food.
Though breeding Longfin Diamond Neon Tetras demands meticulous care and precision, the resulting excitement of seeing the birth of new life within your aquarium provides an immensely satisfying experience.
Diet & Feeding
Maintaining a diverse diet is essential for the health of Longfin Diamond Neon Tetras, and luckily, these fish are not fussy eaters. It's recommended to provide them with high-quality flakes and granules as their primary sustenance, supplemented with live and frozen foods like bloodworms, brine shrimp, and daphnia, to prevent potential nutritional deficiencies.
In addition to these, micropellet food can be a beneficial addition to their diet. Consider opting for tropical sinking pellets enriched with natural colour enhancers, as these contribute to amplifying the Longfin Diamond Neon Tetras' vibrant colours. These varied dietary offerings play a crucial role in promoting their overall health and vitality.
