🌟 Glowlight Tetra (Hemigrammus erythrozonus) – Complete Care & Aquarium Guide

The Glowlight Tetra (Hemigrammus erythrozonus) is a strikingly beautiful freshwater fish that has become a favourite in community aquariums worldwide. Recognisable by its glowing copper-orange stripe that runs along the length of its body, this tetra seems to shimmer under aquarium lighting, bringing colour and movement to any aquascape. Native to the clear and slow-moving streams of Guyana in South America, the Glowlight Tetra is both hardy and peaceful, making it an excellent choice for aquarists of all experience levels.

When kept in a group, these fish display their natural schooling behaviour, darting together across the tank in a way that creates both harmony and visual appeal. They thrive in aquariums that replicate their natural habitat – planted with live aquatic vegetation, decorated with driftwood or fine roots, and equipped with subdued lighting that enhances their iridescent glow.

📖 Natural Habitat and Behaviour

In the wild, Glowlight Tetras are found in soft, slightly acidic waters with a sandy or silty substrate, shaded by overhanging vegetation. They are naturally peaceful and thrive in shoals, using their numbers as protection against predators. In captivity, this behaviour remains unchanged, which is why aquarists are encouraged to keep them in groups of six or more. The larger the group, the more confident and colourful the fish will appear.

🐟 Care Requirements for Glowlight Tetras

Keeping Glowlight Tetras is straightforward, as they are a hardy species that adapts well to a range of aquarium conditions. However, optimal care will ensure their health, longevity, and brightest colours.

🌿 Aquarium Setup

To bring out the natural beauty of the Glowlight Tetra, a well-planted aquarium with a dark substrate works best. Plants such as Java fern, Amazon swords, and floating plants provide both cover and shade. A gentle water flow mimics their natural habitat and keeps them comfortable. Avoid bright, harsh lighting as it may stress the fish; instead, subdued lighting enhances their glowing stripe and creates a more natural feel.

🍽️ Feeding Glowlight Tetras

As omnivores, Glowlight Tetras are easy to feed and accept a wide variety of foods. A high-quality tropical fish flake or micro-pellet should be the staple of their diet, supplemented with frozen or live foods like brine shrimp, daphnia, and bloodworms. This variety ensures they receive essential proteins, vitamins, and nutrients that enhance both their colours and overall vitality. Feeding them small portions two to three times daily is ideal.

🤝 Compatibility and Tankmates

Glowlight Tetras are renowned for their peaceful temperament, making them excellent community fish. They coexist happily with other small, non-aggressive species.

Ideal tankmates include:

• Other small tetras (Neon Tetras, Cardinal Tetras, Ember Tetras)

• Harlequin Rasboras and other peaceful schooling fish

• Corydoras catfish and small loaches

• Peaceful dwarf gouramis

• Freshwater shrimp and snails

It is important to avoid housing them with aggressive or much larger species such as large cichlids or fin-nippers, as Glowlight Tetras are small and delicate.
