What Glowlight Danio look like

Celestichthys choprae, commonly known as the Glowlight Danio, exhibits a fusiform body shape that typically reaches a maximum adult size of approximately 1.5 to 2 inches (4 to 5 cm). The species is characterized by a dark, almost black body adorned with striking, vivid neon orange-gold vertical bars and stripes, a unique feature that distinguishes it from other danios which often display horizontal striping. This striking coloration serves not only as a visual cue for mating but also as a potential warning to predators. The Glowlight Danio possesses a well-developed lateral line system, which aids in detecting movement and vibrations in the water, enhancing its schooling behavior. Its dentition is small and numerous, adapted for an omnivorous diet, while the presence of an adipose fin contributes to its streamlined swimming efficiency. Sexual dimorphism is subtle, with males typically being slightly smaller and exhibiting more vibrant coloration compared to females, particularly during breeding periods.

Behavior & temperament

The Glowlight Danio is a highly active, obligate schooler, typically found in mid-water regions of its habitat. It thrives in groups, displaying a clear social hierarchy where dominant individuals often exhibit more vibrant coloration and assertive behaviors. This species is known for its peaceful temperament, making it an excellent community fish. Breeding behavior is characterized by egg scattering, where females release eggs into the water column, allowing males to fertilize them externally. The Glowlight Danio exhibits minimal aggression, preferring to engage in social interactions rather than territorial disputes, which further enhances its suitability for community aquariums.

Diet & feeding

In the wild, the Glowlight Danio is an omnivore, consuming a varied diet that includes small invertebrates, zooplankton, and plant matter. In captivity, it requires a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to ensure optimal health and coloration.
