Arulius Barb (Dawkinsia arulius, Puntius arulius)

Arulius Barbs are and active shoaling species that should be kept in groups of eight or more. Maintaining them in smaller groups will make them feel unsafe and prevent them from displaying their true colours. They may also harass other fish species if kept in too small a group.

An Arulius Barb is an excellent choice for any community aquarium containing mid-sized species that enjoy a similar environment. The fast-moving species should not be kept with timid species that might be spooked or stressed by it.

As with many Barbs, Arulius Barbs can display some nippy behaviour toward other fish; however, if you keep them in significant numbers in your aquarium, you can avoid this.

Araulius Barbs adapt well to most aquarium conditions as long as the water quality is pristine. A few hiding places in an aquarium, however, enhance the colouration of these fish. As a result, you should create an aquarium with areas of dense vegetation and open spaces for this fast-moving fish to swim around in. When keeping Aurulius Barbs, a few shaded areas among roots are also appreciated, and filtration is essential.

The backs of Arulius Barbs are dark brownish-olive, and their sides are lighter. On their ventral surface, these fish also have white shading. Additionally, they have a black vertical patch at the middle of their body, above their pelvic fin, a black vertical blotch above their anal fin, and a third black bar or blotch at the base of their caudal fin. However, these marks are not as defined as the other two blotches. These fish's anal and caudal fins display some reddish hues, and their Dorsal fin is long and flowing, often striped with grey or black. The colours of adults are more pronounced than those of juveniles.

Feeding

In the home aquarium, the Arulius Barb 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 straightforward to differentiate between male and female Arulius Barbs when they are adults; however, it is harder to sex these fish with juveniles. Males are usually more vibrantly coloured, have more intense colour patterns, and are usually more slender than females. In addition, when adult males are in spawning conditions, they present white dots around their mouths. This can look similar to a disease, but if the spots are focused only on the mouth, it is probably just the spawning pattern of this species. In contrast, females are rounder bodied and somewhat duller than males.
