Brighten up your aquarium with Hemigrammus erythrozonus (commonly known as the Glowlight Tetra), one of the most classic and elegant freshwater fish in the hobby. Instantly recognizable by the brilliant, neon orange-red horizontal stripe running across its translucent body, this peaceful schooling species creates a mesmerising visual effect as it glides through planted tanks.

Note for Beginner Aquarists: Glowlight Tetras are exceptionally hardy, peaceful, and forgiving of initial beginner mistakes. Because they thrive in community settings and eat a wide variety of standard foods, they serve as an ideal entry-level species for first-time fishkeepers looking to build a colorful, active aquarium.

Product Overview & Highlights

The Glowlight Tetra is an active, mid-to-bottom dwelling schooling fish that performs best when kept in groups of 6 or more. They thrive in aquariums with moderate lighting, dark substrates, and live plants, which cause their vibrant neon stripes to pop dramatically.

Comprehensive Beginner Care Guide

1. Tank Setup & Environment

• Schooling Behavior: Always keep Glowlight Tetras in a group of at least 6 (preferably 8–10+). Schooling provides them with safety, reduces stress, and showcases their natural swimming dynamics.

• Aquarium Decor: Decorate with real or silk plants (such as Java Fern, Anubias, or Amazon Swords) and driftwood. Darker substrates enhance their bright orange-red stripe.

2. Water Parameters & Maintenance

• Perform weekly 15% to 20% water changes to keep nitrate levels low.

• Maintain a stable water temperature with a reliable heater. Avoid sudden temperature or pH swings when adding new fish.

3. Feeding Guidelines

• Offer a balanced diet consisting of high-quality tropical flakes or micro-pellets daily.

• Treat them once or twice a week to frozen or freeze-dried foods like bloodworms, daphnia, or brine shrimp to support peak health and vivid coloration.
