Table of contents
Introduction
The Rohani Barb, (Dawkinsia Rohani) is a peaceful and stunning shoaling species that shares many similarities in appearance with the elusive Mascara Barbs. Despite their larger size, these fish are non-aggressive and blend well with other fish in a community aquarium setting. To ensure the happiness and comfort of these gorgeous fish, it' s recommended to keep them in groups of no less than six, with larger groups being even better. This helps to reduce skittish behavior and creates a more natural-looking display. Additionally, it' s important to use a tight-fitting lid when introducing them to the aquarium, as they are known to be active jumpers. Creating the ideal aquarium environment for Rohani Barbs involves incorporating a range of features, including rocks of varying sizes, pebbles, sand or fine gravel, and small boulders as a substrate. Hardy aquatic plants are also highly recommended, as well as driftwood for added natural appeal. When it comes to appearance, the Rohani Barb is truly a sight to behold. These fish boast an aluminous yellow-green fishnet pattern across the top half of their body, which contrasts beautifully with their silver and black teardrop mark above the tail. Their dorsal fin is a striking red and black, while the caudal and anal fins are reddish, and the pectoral and pelvic fins are transparent. Together, these features create a visually stunning fish that is sure to captivate any aquarium enthusiast.Rohani Barb Photos
Sexual Dimorphism
Distinguishing between male and female Rohani Barbs is a relatively straightforward process. Generally speaking, females tend to grow larger than males and have heavier, less colorful bodies once they reach maturity. On the other hand, males boast a more vibrant color pattern and exhibit distinct physical characteristics during the spawning season. Specifically, mature males will display a reddish glow in the central region of their body and develop visible tubercules on their heads. It' s also worth noting that the dorsal fin of both male and female Rohani Barbs may produce filamentous rays that shed or absorb depending on the season. This fascinating trait adds to the allure of these unique fish and provides further insight into their behavior and natural habitat.Quick Facts

Natural habitat
The Rohani Barb is a captivating fish that can be found exclusively in Tamil Nadu State and Kanyakumari District, nestled within the stunning Western Ghats mountain range in South India. These fascinating Barbs thrive in the flowing waters of hill streams that eventually drain into the Arabian Sea. Although these fish are typically found in hill streams, their natural habitats can vary depending on location and the time of year. This is due in part to the two seasonal monsoons that cause fluctuations in water depth, turbidity, and flow in the rivers where they reside. These ever-changing conditions help make the Rohani Barb a highly adaptable and resilient species, capable of thriving in a range of different environments. Overall, the Rohani Barb is a testament to the unique and diverse ecosystem of the Western Ghats mountain range. Its ability to thrive in the face of changing conditions is a testament to its remarkable adaptability and makes it an intriguing species for any aquarium enthusiast to explore.How to breed the Rohani Barb
Rohani Barbs are a type of egg-scattering fish that tend to spawn readily under favorable water conditions. In established aquariums, it' s not uncommon to see small numbers of fry appear without any intervention. To optimize the breeding process, it' s recommended to set up a separate tank that is dimly lit and has a bottom covered with mesh or plastic grass matting, or a layer of glass marbles. Alternatively, filling much of the tank with fine-leaved plants or spawning mops can also yield good results. The water in the tank should be slightly acidic to neutral and kept at a slightly higher temperature than usual, with an air stone or air-powered sponge filter included to provide adequate water movement and oxygenation. Once the adults are well-conditioned and the females appear full of eggs, one or two pairs should be introduced to the tank, and spawning should begin the following morning. Alternatively, spawning can also be done in a group with six individuals of each sex being an ideal number, though a larger aquarium may be necessary. It' s important to note that the adults are likely to consume the eggs if given the opportunity, so prompt removal of the eggs is advisable. The eggs should hatch within 24 to 48 hours, and the fry will become free-swimming around 24 hours after that. During this early stage, the Barbs require microscopic food until they are big enough to accept artemia, microworm, and nauplii. By following these guidelines, breeders can increase their chances of successfully breeding Rohani Barbs in a controlled environment.Diet & feeding
Maintaining optimal health and vibrancy of the Rohani Barbs in a home aquarium requires a varied and nutritious diet. While these fish are relatively easy to feed, a diverse diet is essential for achieving optimal color and overall condition. Incorporating small live and frozen foods such as daphnia, bloodworm, and artemia into their diet, in addition to high-quality dried flakes and granules, will provide the essential nutrients they need to thrive. By offering a balanced mix of protein, carbohydrates, and vitamins, aquarium owners can help ensure the long-term health and vitality of their Rohani Barbs. A well-rounded and nutritious diet is a critical aspect of maintaining a healthy and vibrant population of Rohani Barbs in the home aquarium. By providing a variety of nutrient-rich food sources, these fascinating fish can thrive and showcase their full potential.Other Barbs you maybe interested in
