Glowlight Danio (Celestichthys choprae)

Glowlight Danios are very peaceful, stunning fish, making them an ideal resident of a community tank. Since these Danios have no particular demands when it comes to water chemistry, you can combine them with most fish in the hobby, including other small Cyprinids, Tetras, livebearers, Rainbowfish, Catfish and peaceful Loaches.

Glowlight Danios are schooling species by nature; therefore, you should keep them in a group of 8 to 10 individuals. These fish will develop a pecking order among themselves. In addition, maintaining glowlight danios in more significant numbers will not only help make the fish less nervous but will also allow the lesser dominant fish of both sexes some respite from the alpha males, which can be pretty aggressive at times.

Glowlight Danios will thrive if you maintain them in a well-planted aquarium or a set-up created to mimic a flowing river or stream, with a substrate of different sized rocks and gravel and some large smooth boulders.

You can use additional powerheads or filter outlets to provide a decent flow; however, you should avoid torrent-like conditions since small Danios tend to occupy calmer waters and marginal zones in nature. These fish also appreciate hardy aquatic plants that can be grown attached to the decor, as well as branches and driftwood roots.

A tight-fitting lid for your aquarium will also be required as this species is an accomplished jumper and can fir through the smallest gaps.

The bodies of Glowlight Danios are slender and shaped like torpedoes. Greenish-golden bodies are adorned with blue vertical bars and a blue horizontal bar running dorsally across the entire body. In contrast with the translucent fins, the caudal fin has a black and gold tip. Additionally, a yellow line runs horizontally across the dorsal fin. Finally, there is a white line across the anal fin.

In the home aquarium, the Glowlight Danio will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Frequently asked questions

How big do Glowlight Danios get?

Glowlight Danios are one of the smallest Danio species, reaching just under 3 cm in length, with the males being slightly smaller than the females.

How long do Glowlight Danios live?

Glowlight Danios typically live between one and three years, depending on their quality of life. However, with the proper care, these fish could live up to 5 years.

What do Glowlight Danios look like?

Glowlight Danios are a small fish with a sleek body and a barbel at the tip of each lip. Glowlight Danios have stunning colouration and patterning composed of bars, stripes and spots. This fish looks very similar to the Pearl Danio with its yellow, brown, and green colouring. However, Glowlight Danios have bright orange stripes on the back half of their body with green, red, turquoise and gold spots.

What should you feed Glowlight Danios?

Glowlight Danios are omnivores that will accept most fish food. However, these fish are pretty active and have high nutrient requirements, so choose good quality dry food that will accommodate their needs. This could include flakes and granules alongside regular meals of small frozen and live food such as Daphnia, bloodworm, and Artemia to get the best condition and colouring from your fish. Glowlight Danios will do best when offered food several times a day; however, only give them what they can eat in under 3 minutes. If you can only feed your fish once a day, provide them with what they can consume in around 5 minutes.

What size aquarium do Glowlight Danios need?

You can house a small school of Glowlight Danios in a 45-litre aquarium, although a 90-litre aquarium will suit them better. Another fact that might be good to know is Glowlight Danios can appear somewhat washed out if the tank does not have enough decor, so make sure you have plenty of plants and suchlike. Finally, to display this fish's best colours and make them stand out, you should use a darker substrate.

What tankmates are suitable for Glowlight Danios?

Glowlight Danios are somewhat shy fish; therefore, you should keep them with small peaceful fish or in a species only aquarium. Large tankmates, friendly or not, usually scare them into hiding. However, they thrive with other small Cyprinids and Danios, except for the Giant Danio, which is much bigger and will often harass smaller fish. You can also mix them with most Tetras, Rainbowfish, Livebearers, Catfish, Loaches and Anabantoids.
