Scientific name: Epalzeorhynchus bicolor
The Red-Tailed Shark is not really a shark, despite its triangular dorsal fin and its common name. It grows to a length of five inches and is not particularly fond of its own kind. Either just one or a group of at least four or five should be kept in a tank. It is best to provide hiding places, and the Red-Tailed Shark prefers to have strong currents in the tank.
The Red-Tailed Shark is among the more attractive bottom dwellers, but its color will fade in poor-quality water. A water temperature of 74º to 82º Fahrenheit, a neutral pH of 6.8 to 7.2, and water that is moderately soft to slightly hard are suitable. It does well on flake and freeze-dried foods.
