Laos Danio (Devario Laoensis)

Laos Danios are peaceful, reasonably hardy and active, making them suitable for beginner hobbyists and an excellent addition to a spacious, peaceful community aquarium.

Laos Danios are a shoaling species in nature; therefore, it would be better to maintain them in groups of six or more individuals. Suitable tankmates for these Danios could include other small Cyprinids, other Danio species, most livebearers, Tetras, Rasboras, bottom-dwellers such as Catfish and Loaches, Gobies, and Dwarf shrimp. You can also keep these Danios with the most commonly available Gouramis and Dwarf Cichlids. However, smaller species, fish with intricate finnage or slow-moving fish, are not recommended.

The aquarium should have a reasonable flow rate and be well-oxygenated as these fish will enjoy swimming against the current, like most Danio species. Since these Danios naturally occur in pristine habitats, they are intolerant to the buildup of extreme organic pollutants. Therefore these fish require good water conditions to thrive, and you should never introduce them into a biologically immature aquarium. The aquarium will need a tight-fitting cover as Laos Danios have periods of skittish behaviour and are inclined to leaping out of the aquarium.

Unfortunately, there is little to no information on how to care for these fish in captivity; however, they shouldn't be too difficult to keep in a well-maintained setup like other Danio species.

Laos Danios are likely to thrive in an aquarium setting resembling a flowing river or stream with a substrate of differently-sized smooth rocks, some sand or fine gravel and maybe some smallish stones. You can also add driftwood roots or branches and hardy aquatic plants like Anubias, Microsorum and Bolbitis.

Laos Danios have a silvery bronze body that displays a dark, lateral stripe on their mid-body that is relatively faint, extending through the body, becoming thicker and darker on the posterior part of the body and ending at the caudal fin. The dark lateral stripe also has two broken orange lines within it. In addition, these fish also have a central bar on their anal fin and a submarginal stripe on their dorsal fin.

Feeding

In the home aquarium, the Laos 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.

Sexual Dimorphism

It can be somewhat challenging to distinguish the males from the female Laos Danios. Sexually mature females are usually rounder-bellied, less colourful and a little larger than males. Also, When in breeding conditions, the dominant males lower half of the body becomes bright orange.
