Rohani Barb (Dawkinsia Rohani)

Rohani Barbs, Dawkinsia Rohani, are peaceful and lovely shoaling species, similar in appearance to the rarer Mascara Barbs. Despite their large size, these fish are non-aggressive and blend well with other fish.

These Barbs should be kept in groups of no less than six, with larger groups being better. It will make the fish less skittish and result in a more natural-looking display when they are kept in more significant numbers. It is important to use a tight fighting lid when introducing them; otherwise, they may jump out.

The ideal aquarium for Rohani Barbs would incorporate rocks of varying sizes, pebbles, sand or fine gravel, and perhaps some small boulders as a substrate. Your fish would also benefit from driftwood and hardy aquatic plants such as Microsorum or Anubias.

There is an aluminous yellow-green fishnet pattern across the top half of the Rohani Barb's body, contrasted with silver and a black teardrop mark above the tail. The dorsal fin is red and black, the caudal and anal fins are reddish, and the pectoral and pelvic fins are transparent.

In the home aquarium, the Rohani 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

Male and female Rohani Barbs can be distinguished relatively easily. Females usually grow larger, have heavier bodies, and are less colourful as adults.

Males have a more striking colour pattern and when in spawning conditions, mature males display a reddish glow in the central region of their body and visible tubercules on the head.

The dorsal fin of both sexes may produce filamentous rays that shed or absorb depending on the season.
