Red Tailed Black Shark (Epalzeorhynchos bicolor)
The Red Tailed Black Shark originates from freshwater rivers and floodplains in Thailand. In the wild, their populations are now endangered, but they are widely bred for the aquarium trade. This species’ striking color contrast, velvety black body with a vivid red tail, instantly draws attention, and their energetic swimming adds dynamic movement to your tank.
In home aquariums, red tail sharks typically grow to 4–6 inches (10–15 cm), with a sleek, torpedo-shaped body and forked tail. When kept in optimal conditions, their coloration becomes even richer, with the tail displaying a fiery glow against their dark body.

The shark is very active and adds a lot of visual interest to my 55-gallon tank. The red tail stands out beautifully against the dark body. I’ve kept it for six months and it’s healthy and swimming well.

It’s a striking fish with a unique appearance. The coloration is vibrant, especially in good lighting. I do need to ensure the tank has plenty of hiding spots since it can be slightly territorial.

I was impressed by how quickly it adapted to the tank. The movement is energetic and the red tail is very noticeable. I recommend a minimum tank size of 55 gallons for proper space.
