Silver Shark 6cm, also known as Bala Sharks, are one of the more commonly kept species in the aquarium hobby. This incredible species of tropical fish is not actually a true Shark but is aptly named due to their Shark-like appearance.
 
Juvenile Balas are often only small and as a result are a great addition to a community tank. Mature Silver Sharks will eventually grow quite large, so if you are planning on keeping them long-term it is worth ensuring you have a suitably large aquarium. 
 
Despite their large size Silver Sharks are actually a very peaceful fish. They are very social and should be kept in a groups of more than two. This will allow them to shoal, which is a natural behaviour of the Silver Shark.
