Table of contents
Introduction
The Red-tailed Black Shark (Epalzeorhynchos bicolor ) is a distinctive freshwater fish that has garnered considerable attention within the aquarium hobby for its striking appearance and dynamic behavior. Originating from Thailand, this species is characterized by its vivid black body contrasted sharply by a vibrant red tail, making it a visually appealing addition to any aquarium. Despite its common name, it is not a true shark but belongs to the Cyprinidae family, which includes Carps and Minnows. The Red-Tailed Black Shark is known for its territorial nature, especially towards conspecifics, necessitating thoughtful consideration in community tank setups to ensure harmonious cohabitation.
Red-tailed Black Sharks exhibit pronounced territorial behaviors, necessitating solitary housing in smaller aquariums to prevent conflicts, especially with species of similar appearance. Optimal conditions for maintaining these fish involve grouping them within a spacious, intricately arranged habitat. This approach not only mitigates aggressive tendencies but also promotes natural, vibrant social interactions among the group, enhancing the overall well-being of the species in captivity.
When selecting companions for Red-tailed Black Sharks, it is advisable to choose larger, vigorous, and sturdy schooling fish from the Cyprinid family, including species like Mascara Barbs, Denison Barbs, Odessa Barbs, and Clown Barbs. It is crucial, however, to steer clear of species with similar appearances, such as the Rainbow Shark and True Flying Fox. These resemblances can trigger competitive behavior, as they are likely to be perceived as competitors, potentially escalating into aggression.
Enhancing the aquarium with an arrangement of rocks, pebbles, and driftwood, complemented by resilient aquatic flora, affords numerous concealment spots for your fish, contributing to their sense of security and well-being. Emulating their indigenous environment through the creation of a stream or river-like setting, complete with a substrate of sand or fine gravel and interspersed with boulders, represents an optimal setup. Ensuring the health and contentment of these fish mandates the upkeep of exemplary water conditions, achieved through efficient filtration and regular water changes. Given their propensity to leap, securing the aquarium with a well-fitted lid is imperative to prevent escape.
As juveniles, the Red-Tailed Black Shark is jet black with a bright red caudal fin, but as they mature, their colour fades to a dark grey. Their chunky torpedo-shaped body and dorsal fin halfway down their back give them a striking shark-like appearance that is sure to impress. In summary, the Red-Tailed Black Shark is an impressive and exciting fish that will undoubtedly be a highlight in any aquarium. With proper care and attention, these fish will thrive and display their stunning colours and behaviours for years to come.

Sexual Dimorphism
It can be challenging to distinguish between male and female Red-tailed Black Sharks when they are immature. However, once they reach maturity, there are some visible differences between the sexes. Typically, the male's caudal fin is brighter than the female's and appears slightly slimmer. Additionally, the males tend to develop longer extensions to their dorsal and anal fins. In contrast, female Red-Tailed Black Sharks are larger, and plumper than males, and their overall colouration is slightly duller.

Diet & Feeding
Ensuring a nutritious and well-rounded diet is critical for the health and vivid coloration of the Red-tailed Black Shark. A foundation of their nutritional regimen should be high-quality dry foods, including flakes, granules, and pellets. To complement this, incorporating live and frozen options, such as bloodworms, daphnia, mosquito larvae, and brine shrimp, is imperative for providing a comprehensive spectrum of essential nutrients. Given their natural propensity for algae grazing, the inclusion of plant-based supplements, like spirulina or algae wafers, is recommended. A diversified diet is key to maintaining the well-being and vibrancy of Red-Tailed Black Sharks in captivity.
