Barred Danio (Devario pathirana)

Barred Danios are a slightly larger Danio species but, unfortunately, are pretty rare in the aquarium hobby. However, these Danios are reasonably attractive, peaceful, quite active and hardy, making them suitable for beginner or more advanced aquarist. In addition, these Danios make excellent members of a community aquarium with similarly-sized, robust, peaceful species.

Ideal tankmates for Barred Danios could include larger Cyprinids such as Barbs, larger Tetras, loaches, Cichlids and Catfish. However, it would help if you avoided housing these Danios with slow-moving or shyer tankmates as their constant activity and lively feeding behaviour may upset other species. It would also help to avoid tankmates with long trailing fins as these fish will nip at them.

Barred Danios are shoaling fish in nature; therefore, it would be best to keep them in groups of at least six individuals, preferably more. Keeping these Danios in larger groups will make your fish feel more comfortable and will give your aquarium a more natural-looking display. The males will also display their best colours as they compete with one another for female attention. In addition, these Danios are more contentious than most Danios; therefore, maintaining these fish in decent numbers is helpful because this will generally restrict any aggressive behaviour to their own kind or other weaker species.

It would be better to maintain Barred Danios in a well-planted aquarium or an aquarium designed to mimic a flowing stream or river with a substrate of gravel, different sized pebbles or a few large smooth rocks. You can use additional powerheads or filter outlets to provide flow; however, you should avoid fast currents because these fish usually occupy calmer waters in the wild. It would also suit your Danios if you added driftwood roots and branches and hardy aquatic plants such as Anubias, Microsorum or Bolbitis.

Barred Danios naturally occur in pristine habitats; therefore, they are intolerant to the build-up of organic waste and require very clean water to thrive, so weekly water changes are essential. You will also need a tight-fitting lid on your aquarium as Danios are exceptional jumpers and can fit through the smallest gaps.

Barred Danios have a silvery-grey body with 7 to 11 dark blue, oddly-shaped, parallel upright bars on the front portion of each flank with goldish colouration in between the bars. These Danios also have a short horizontal stripe on the caudal peduncle that spreads into the central caudal-fin rays. In addition, these Danios have relatively large eyes, and all their fins are transparent.

Feeding

In the home aquarium, the 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 distinguish between the female and male Barred Danio. The males are somewhat smaller, slimmer, and more intensely coloured than females. In contrast, females are slightly larger, have fuller bodies, especially when gravid and are much duller than males.
