Borneo Red Fin Silver Shark - Cyclocheilichthys janthochir : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Borneo Red Fin Silver Shark (Cyclocheilichthys janthochir) is an elegant, peaceful, and rare species in the aquarium trade, making them a unique addition to any tank. These fish thrive in groups of at least six individuals in a spacious aquarium of 300 liters or more, where they can coexist with similarly sized and peaceful fish. Their preferred environment consists of a soft sandy substrate, driftwood, and dense planting, either natural or artificial. Providing these fish with hiding spots and reducing the amount of light with floating plants will help to reduce anxiety, as these fish are easily spooked. It is important to note that the Borneo Red Fin Silver Shark can be intimidated by boisterous or aggressive fish, and placing sharp decor in the aquarium could cause injury. Therefore, we recommend avoiding such decor and providing them with ample swimming space along the front of the tank. The Borneo Red Fin Silver Shark has a torpedo-shaped body with reddish-orange dorsal and caudal fins, and a distinct thin black stripe that runs from their nose to the base of their caudal fin on their pectoral, pelvic, and anal fins. These fish are skittish and easily spooked, so it' s best to keep the aquarium in a quiet area and provide them with tight-fitting lids to prevent them from jumping out.Borneo Red Fin Silver Shark Photos

Natural habitat
The Borneo Red Fin Silver Shark is a fascinating and unique species that calls the dark, tea-coloured waters of the Kapus River in Borneo, Indonesia, home. These elusive creatures are found in blackwater rivers, streams, and old peat swamps, where the presence of decaying vegetation matter creates an environment that is both soft and acidic. The forest canopy overhead provides shade, creating an intricate ecosystem where these sharks thrive. In their natural habitat, Borneo Red Fin Silver Sharks can be seen swimming amidst scattered twigs, leaves, and branches that form the substrate. The tannin-stained waters provide a captivating backdrop that adds to the allure of these intriguing creatures. Keeping these sharks in a home aquarium can provide a unique and captivating glimpse into their natural habitat.How to breed the Borneo Red Fin Silver Shark
To date, there are no documented successful captive breeding attempts of the Borneo Red Fin Silver Shark in the home aquarium setting.Diet & feeding
In captivity, the Borneo Red Fin Silver Sharks are generally considered as undemanding eaters and will readily accept a wide range of food options. However, to ensure that these fish remain healthy and vibrant, it is highly recommended to provide them with a diverse diet. In addition to high-quality flakes and pellets, they should be fed frequent servings of live and frozen foods, such as bloodworms, mosquito larvae, daphnia, artemia, and Mysis shrimp. Larger individuals may also require the addition of krill or finely chopped prawns in their diet. This well-rounded feeding regime will help maintain their excellent colours and overall well-being.Videos
