Glowlight Danio - Celestichthys choprae : Complete Fish Profile & Care Guide

Table of contents


Glowlight Danios (Celestichthys choprae) are incredibly peaceful and visually striking fish, making them perfect candidates for community aquariums. Their adaptability to various water conditions allows them to coexist harmoniously with a diverse range of species, such as other small Cyprinids, Tetras, livebearers, Rainbowfish, Catfish, and docile Loaches. As a schooling species, Glowlight Danios should be kept in groups of 8 to 10 individuals to establish a pecking order and reduce nervousness. Larger groups also offer a reprieve for less dominant fish from the more aggressive alpha males. To ensure the well-being of your Glowlight Danios, provide a well-planted aquarium or a setup that replicates a flowing river or stream. Incorporate a substrate of various-sized rocks and gravel, along with large, smooth boulders. Additional powerheads or filter outlets can be used to generate moderate water flow, but super fast conditions should be avoided, as these fish naturally inhabit calmer waters and marginal zones. Glowlight Danios appreciate sturdy aquatic plants that can be attached to decor, as well as branches and driftwood roots. A tight-fitting lid for the aquarium is essential, as this species is known for its adept jumping ability and can escape through even the smallest gaps. The slender, torpedo-shaped bodies of Glowlight Danios boast greenish-golden hues, adorned with blue vertical bars and a blue horizontal stripe running dorsally across the entire body. In contrast, translucent fins accompany a black and gold-tipped caudal fin. A yellow line spans horizontally across the dorsal fin, and a white line graces the anal fin.

Sexual Dimorphism

Distinguishing between male and female Glowlight Danios is generally a straightforward process. In sexually mature specimens, females tend to exhibit rounder bellies, less vibrant coloration, and a slightly larger size compared to males. During spawning conditions, these differences become more pronounced, as males display intensified coloration and females appear visibly engorged with eggs.

Natural habitat

If you're in search of a strikingly beautiful and unique species to add to your aquarium, look no further than the Glowlight Danio. This captivating fish originates from the river Mogaung Chaung and surrounding small rocky streams in Myanmar, nestled in the vibrant landscapes of Southeast Asia. In the wild, these fish seem to prefer small hill streams with substrates of gravel and rocks of varying sizes, creating a perfect environment for them to thrive. Interestingly, these streams don't seem to contain much, if any, vegetation, which has resulted in the Glowlight Danio developing its unique characteristics and behaviours. So, if you're looking to elevate your aquarium game with a new and exciting species, the Glowlight Danio is a must-have. With their captivating appearance and charming personalities, these fish are sure to make a lasting impression in any aquatic setting.

How to breed the Glowlight Danio

Breeding Glowlight Danios is a relatively simple endeavor, with spontaneous spawning often occurring in community tanks. However, to maximize fry yield, it is advisable to designate a separate breeding tank for these fish. Ensure that delicate plants such as Willow Moss, Java Moss, or Cabomba are present in the aquarium, as females will scatter their eggs among them. Alternatively, incorporating elements like marbles, small rocks, or coarse substrate can provide additional protection for the eggs by making them less accessible to the parents. Following the completion of the spawning process, promptly remove the adult fish from the tank. The fry should hatch within approximately three days and subsequently become free-swimming. Upon hatching, the newly born fry can be nourished with a diet consisting of either liquid or powdered fry-specific food formulations.

Diet & feeding

Glowlight Danios are known for their adaptable dietary preferences, readily accepting a wide variety of food options. A foundation of high-quality dry foods, including flakes and granules, should form the basis of their diet. To optimize their overall health and enhance their coloration, it is essential to supplement their primary diet with regular servings of small frozen and live foods, such as Daphnia, bloodworms, and Artemia.
