Rainbow Sharks are a vibrant species of freshwater fish. Their eye-catching hues and elegant fins make them a popular aquarium addition for experienced and beginner fish keepers.
Rainbow Sharks are omnivores, meaning they feed on plant-based and meaty sources in the wild. They prefer blanched vegetables, small live worms, and other high-quality aquarium foods.
Rainbow Sharks are native to Southeast Asia, living in river systems ranging from the Mekong River Basin to the Malay Peninsula.
They typically inhabit shallow and deeper waters, seeking areas with plenty of submerged logs and rocks.
As juveniles, Rainbow Sharks are silver, though they show hints of both yellow and black as they mature.
Rainbow Sharks reach a maximum size of 6 inches and have a lifespan of up to 10 years with proper care.
They are social creatures who usually prefer to live in groups of 5 or more individuals.
Since they can become territorial, those groups should contain an even number of each sex to reduce quarrels.
Male Rainbow Sharks can be distinguished from the females by their more slender bodies and more colorful fins.
They are relatively undemanding regarding water parameters yet do best in aquariums kept between 78-80°F with a neutral pH.
These fish are nocturnal, so they may not be seen swimming during the day but rather resting in caves and bamboo hides.
