Food and Feeding

Glowlight Danios are omnivorous and thrive on a varied diet. Provide a staple diet of quality flake food, supplemented with live or frozen treats such as bloodworms, daphnia, and tubifex. These additions help maintain vibrant coloration and overall health. To mimic their natural feeding habits, consider feeding them small amounts multiple times a day. Ensure that food particles are appropriately sized for their small mouths.

Origin

Native to Southeast Asia, Danio choprai is endemic to Myanmar. They are commonly found in clear, fast-flowing streams surrounded by dense vegetation. These habitats provide excellent cover and abundant micro-organisms, which form a significant part of their natural diet. Replicating these conditions in the aquarium promotes their well-being and natural behavior.

Sexing

Sexing Glowlight Danios can be challenging, as males and females appear very similar. However, females develop a fuller, rounder body shape when carrying eggs, while males may display slightly more intense coloration during breeding periods.

Breeding

Breeding Glowlight Danios in captivity is possible but requires careful preparation and attention to detail. Set up a separate breeding tank with soft, slightly acidic water and a temperature around 24°C (75.2°F). Add plenty of fine-leaved plants like Java Moss or spawning mops to provide suitable egg-laying sites. These fish typically spawn at dawn, scattering their eggs among the vegetation. Once spawning is complete, remove the parents promptly, as they may consume the eggs.

The eggs hatch within 24-36 hours, and the fry become free-swimming after another 2-3 days. Initially, feed the fry with microscopic foods like Infusoria or commercially available liquid fry food. As they grow, transition them to newly hatched brine shrimp and finely crushed flake food. Note that the fry grow slowly and may take up to six months to reach maturity.

Lifespan

With proper care, the typical lifespan of a Glowlight Danio is 1-3 years. Their lifespan can be extended with excellent water quality, a balanced diet, and a stress-free environment.

Tank Setup and Behavior

Glowlight Danios are peaceful and active schooling fish that thrive in groups of six or more. A well-planted aquarium with open swimming spaces is ideal. Use a sandy or fine gravel substrate and add plants such as Java Fern or Anubias to mimic their natural habitat. Darker substrates and backgrounds enhance their vibrant colors, creating a visually striking display.

Tank mates should include other peaceful species of similar size. Suitable companions include:

Neon Tetras – Small and colorful schooling fish.
Harlequin Rasboras – Peaceful and similarly sized tank mates.
Ember Tetras – Gentle and vibrant additions to a community tank.
Otocinclus Catfish – Perfect for algae control and peaceful coexistence.
Peppered Corydoras – Bottom-dwelling companions that add diversity to the tank.

Avoid keeping Glowlight Danios with large or aggressive fish, as their small size and peaceful nature make them easy targets. Additionally, ensure good water flow to replicate their natural environment, as they enjoy swimming against mild currents.

Short Description

Glowlight Danios are small, active fish with a natural glow-like coloration, making them a beautiful addition to planted aquariums. Their peaceful temperament, schooling nature, and vibrant appearance make them ideal for community tanks. With proper care, these stunning fish will add life and movement to your aquarium setup.
