Diamond Head Black Neon Tetra Care Guide

Introduction

The Diamond Head Black Neon Tetra (Hyphessobrycon herbertaxelrodi) is a visually striking freshwater fish known for its distinctive black and iridescent colours. This species is a favourite among aquarists due to its unique appearance and active schooling behaviour, making it an excellent addition to community aquariums.

Natural Habitat

The Diamond Head Black Neon Tetra is native to the freshwater rivers and streams of South America, particularly in regions of Brazil. They inhabit areas with slow-moving waters, abundant vegetation, and shaded environments, which provide shelter and foraging opportunities in their natural habitat.

Aquarium Setup

A tank of at least 20 gallons is suitable for a small school of Diamond Head Black Neon Tetras, although larger tanks are preferable to provide ample swimming space. The aquarium should be well-planted with live or artificial plants, driftwood, and rocks to create hiding spots and mimic their natural environment. A dark substrate can enhance their vibrant colours; good filtration is important to maintain water quality.

Water Parameters

The ideal water temperature for Diamond Head Black Neon Tetras ranges from 72°F to 78°F (22°C to 26°C), with a pH level between 6.0 and 7.5. They thrive in slightly acidic to neutral water conditions. Regular water changes of about 20-30% per week are essential to keep the water clean and stable for their health.

Diet and Feeding

Diamond Head Black Neon Tetras are omnivorous and will accept a varied diet. They can be fed high-quality flake foods, pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. Including some plant-based foods, like spirulina flakes or blanched vegetables, will help provide balanced nutrition. A varied diet supports their health and enhances their vibrant colours.

Behaviour and Social Structure

This species is known for its peaceful and social nature. Diamond Head Black Neon Tetras do best in groups of at least six or more, as this helps them feel secure and exhibit natural schooling behaviour. They are active swimmers and add dynamic movement to the aquarium, making them an engaging species to observe.

Compatibility with Other Species

Diamond Head Black Neon Tetras are compatible with various peaceful community fish. Suitable tank mates include other tetras, rasboras, guppies, and small catfish. It is important to avoid housing them with aggressive or fin-nipping species that could cause stress or harm to the tetras.

Breeding

Breeding Diamond Head Black Neon Tetras in captivity can be achieved in the right conditions. They are egg scatterers and a separate breeding tank with slightly warmer water (around 76°F or 24°C) and plenty of plants or spawning mops will encourage spawning behaviour. After spawning, the adults should be removed to prevent them from eating the eggs. The fry can be fed infusoria or finely crushed flakes once they hatch.

Health Considerations

Diamond Head Black Neon Tetras are generally hardy but can be susceptible to common freshwater fish diseases such as ich, fin rot, and fungal infections. Maintaining good water quality, providing a balanced diet, and observing for signs of illness are crucial to keeping them healthy. Regular tank maintenance and prompt treatment of any health issues will help ensure their well-being.

Conclusion

The Diamond Head Black Neon Tetra is a vibrant and lively addition to any community aquarium. With proper care, a well-maintained environment, and attention to their specific needs, they can thrive and provide endless enjoyment for aquarists of all levels.
