Amazonian Piranha

For the maverick hobbyist comes offbeat choices. Known for aggressive intent that folklore is made of, pirahnas are actually easy to keep in captivity , as long as they are kept in a species specific habitat. While they do even consume each other when young, in a testament to the theory that only the fittest can survive, as an adult shoal they make a stunning glittering display. High amounts of carnivorous food required dictate that it is difficult to maintain plants alongside these fish, though the desired water chemistry is much the same as an Amazonian planted.
