What to look for when keeping a pirarucu
The pirarucu is the largest species of freshwater fish. It is also a very popular species because it has hardly changed its appearance since about 100 million years ago. However, the pirarucu is a very difficult species to keep in the home because of its fast growth rate and the fact that it can grow up to 2~3 meters in length. Therefore, it is very costly and time-consuming to keep them in an aquarium at least 3 meters long and filled with several tons of water.It is also better to have a powerful filtration system. So, in general, they are mostly kept in large facilities such as aquariums. Pirarucu will be a protected species under the Washington Convention, so most of those distributed in Japan are fry born in Japan. Pirarucu have large scales and powerful bodies. If you are interested in pirarucu, we recommend that you visit an aquarium or a specialty store to see them.
