The pinktail chalceus (Chalceus macrolepidotus) is a species of freshwater fish belonging to the family Chalceidae. They are native to South America, specifically in the Amazon River basin, and are commonly found in rivers and streams with moderate to fast water flow. Pinktail chalceus have a distinctive appearance, with a silver body, a black band along their lateral line, and a bright pink tail. They can grow up to 60 centimeters in length and weigh up to 2 kilograms. These fish are carnivorous and primarily feed on smaller fish, crustaceans, and insects. In the wild, they are known to jump out of the water to catch their prey. In captivity, they require a varied diet that includes live or frozen foods such as bloodworms, brine shrimp, and small pieces of fish. Pinktail chalceus are popular among fish hobbyists due to their unique appearance and active behavior. They are relatively hardy and can tolerate a wide range of water conditions, but they require a large tank with plenty of swimming space and strong water flow. They can be kept with other large, peaceful fish, but may become aggressive towards smaller fish or fish with long fins. Overall, the pinktail chalceus is an interesting and attractive fish species that can make a great addition to a large, well-maintained aquarium.
