Fire Bar Danio (Devario maetaengensis)

Fire Bar Danios are a peaceful, active, and hardy fish species, making them ideal for the general community aquarium and suitable for beginner aquarists. You can house these fish with many of the most popular fish in the hobby, including Barbs, Tetras, Cichlids, Loaches and Catfish. However, it would be best if you did not house these Danios with much larger, more aggressive species; otherwise, they will feel intimidated and will be outcompeted for food.

Fire Bar Danios are schooling species in the wild, so they should be kept in a group of at least eight individuals, preferably more. Keeping these Danios in more significant numbers will make your fish less nervous and result in a more sufficient, natural-looking array. In addition, this will manage any aggression because the fish will be concentrating on maintaining their hierarchical position within the group. Males will also display better colours when they are in the presence of rivals. It would be best if you did not keep these fish in very small groups or individually; otherwise, they will become easily stressed and more prone to illness.

Fire Bar Danios will do best in an aquarium set up designed to mimic a flowing river or stream. The substrate can be sand or gravel with differently sized boulders or smooth rocks. You can further furnish the aquarium with driftwood or bogwood and hardy aquatic plants such as Anubias or Microsorum.

Fire Bar Danios come from pristine waters; therefore, they are somewhat intolerant to the build-up of organic waste, so make sure you keep the water clean by performing regular water changes. These Danios do not require a fast current as the water flow in their natural habitat is moderate; however, they do prefer a high proportion of dissolved oxygen. Finally, the aquarium will need to have a tight-fitting lid as these Danios are excellent jumpers.

Fire Bar Danios have a relatively stocky copper-coloured body that sports a solid dark lateral line that extends into the caudal fin. In addition, these fish display a series of vertical bars that become gradually deeper then slowly shorter. The number of vertical bars can be variable on individual species. All the fins on these fish are transparent.

In the home aquarium, the Fire Bar 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 is relatively simple to differentiate between male and female Fire Bar Danios. The males are usually slimmer, somewhat smaller and much bolder in colour than females, especially when they are ready to breed. In contrast, Sexually mature females are generally deeper-bodied, less colourful, and grow slightly bigger than males.
