Redtail Shark by LiveAquaria
The Redtail Shark, also known as the Redtail Black Shark, is ideal for a semi-aggressive community aquarium when kept alone and with tankmates of similar size. This fish features a jet black body with a bright red tail and a white-tipped dorsal fin.
It thrives in a large aquarium with driftwood, rocks, and areas of dense vegetation. The fish may establish territories and can become highly aggressive toward its own kind as it matures.
As an omnivore, the Redtail Shark accepts a variety of foods including flake food, freeze-dried bloodworms, tubifex, and vegetable-based foods.

The Redtail Shark is a striking addition to my aquarium. The red tail stands out beautifully against the dark body. I keep it alone and have added plenty of driftwood and plants. It’s active and curious, but I’ve noticed it patrols the edges of the tank. Feeding is easy with flake and bloodworms. Just make sure not to add any other sharks.

Great visual appeal. The white tip on the dorsal fin and bright red tail make it a centerpiece. I’ve maintained a 120-gallon tank with rocks and dense plants. It’s not overly aggressive with my other fish, as long as they’re not small or shy.

It’s a beautiful fish, but I’ve seen it become territorial after a few months. I keep it alone and have avoided adding any other fish. Feeding is straightforward, but I do notice it spends a lot of time near the back of the tank.
