Red-tailed Black Shark

Red-tailed Black Sharks are known for their deep black color and the vividly colored tails. Their tail colors come in several colors with bright red and orange being the most common. When two Red-tailed Sharks are cohabitated together, they have been known to become territorial with one another. The dominant shark will continually chase and harass the submissive shark, preventing it from feeding and resting. This will often result in the death of submissive Red-tailed Shark. However, they are generally considered compatible in community tanks, inter-species conflict being relatively rare.
