The Rainbow Shark, also known as Epalzeorhynchos frenatum, is a striking and active freshwater fish species that originates from Thailand. With its vibrant colors and energetic personality, the Rainbow Shark is a popular choice for aquarists looking to add some excitement to their aquarium.


Rainbow Sharks can grow up to 6 inches in length and require a minimum tank size of 55 gallons. They are active swimmers and appreciate plenty of hiding places and decorations in their environment. It's important to provide a well-filtered and well-aerated tank, as Rainbow Sharks prefer well-oxygenated water.


These carnivorous fish will eat a variety of foods, including flakes, pellets, and live or frozen meaty foods. It's important to provide a balanced diet to ensure they receive all the necessary nutrients for optimal health.


The Rainbow Shark's unique characteristic is its vibrant red tail and black body, which gives it a striking appearance in any aquarium. They are known for being territorial, especially towards other fish with similar body shapes, and are best kept alone or in a larger aquarium with plenty of hiding places.
