Do Cardinal Tetras Jump?
Cardinal tetras are one of the most popular types of pet fish, and they’re easy to care for. However, there is some debate on whether or not this species actually jumps out of tanks (or an argument about how often it does). Although Cardinal tetras can jump, they are less likely to do so than other species, and they don’t do it with the frequency or regularity of betta fish.
Cardinal tetras are native to South America in places like Brazil, Venezuela, and Columbia. Their natural habitat consists of slow-moving rivers where they swim up and down over sandy substrates. Cardinal tetras are also present in the aquarium trade, but they have become less common lately due to the depletion of wild populations.
