Black Barred Danio (Danio absconditus)

The black-barred Danio is a peaceful, hardy, active, and friendly species. In contrast to schooling fish, Danios form groups when they feel threatened rather than shoaling.

It is advisable to maintain these fish in groups of 10 or more individuals; this will allow sub-dominant fish of both sexes to get a break from the alpha fish, which can be somewhat aggressive at times.

Cyprinids, Cichlids, larger Tetras, Loaches, and Catfish make excellent tankmates for Black-barred Danios. However, it would be best to avoid slow-moving or timid fish as these Danios may upset them with their endless activity and robust feeding behaviour.

As members of this genus are skilful jumpers and can fit through small gaps, you must ensure your aquarium cover fits tightly.

The black-barred Danio has a greyish brown body colour with 7 to 11 dark vertical bars on the abdominal area. At the base of the caudal fin, these fish also have an elongated or round black spot. Females have transparent fins, and males have yellowish-orange caudal fins and a soft black edging on their anal and dorsal fins.

In the home aquarium, the Black Barred 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 simple to differentiate between a male and a female Black-barred Danio. Adult males are much more colourful and noticeably slimmer, plus they have orange distal edges to the anal and ventral fins. In contrast, females have more rounded bodies, especially when they are full of eggs, are slightly duller than males and display white distal edges in their anal and ventral fins.

If you have groups containing various males, one or more individuals can typically develop an alpha status and display more intense colouration.
