The Red Tail Shark (Epalzeorhynchus bicolor) has a black body with a red tail and sort of resembles a shark (hence the name). It is best to keep one Red Tail shark in your tank because they will become very aggressive and territorial towards each other when kept in multiples. Avoid the temptation to keep them with a Rainbow Shark or other Red Tailed Sharks.
Many hobbyists mistakenly add multiple Red Tail Sharks to a small tank only to find out that one of them will soon become the dominant "shark". The dominant one will chase and pester the others relentlessly. Any time the submissive sharks try to get to food the dominant one will chase it away. They really can become quite obnoxious which is why we recommend keeping only one unless you have a much larger tank.
Provide your Red Tail Shark with many hiding places to help make them feel secure and have a tight fitting hood because they are also known to be excellent jumpers.
The Redtail Shark, also known as the Redtail Black Shark is great for the semi-aggressive community aquarium, as long as they are the sole sharks and the other tankmates are of similar size. The Redtail Shark is a beautiful fish with a jet black body and a bright red tail. The dorsal fin is marked with a white tip.
It requires a large aquarium with driftwood, rocks, and spots of dense vegetation. This shark may set up territories around the aquarium. The Redtail Shark will become very aggressive towards its own species when mature.
