Bala Shark

(Balantiocheilos melanopterus) 

The Bala Shark is also known as the Silver Shark and is a growing favorite among tropical fish hobbyists. This fish isn't a shark at all though. It belongs in the Cyprinidae family. They are commonly named silver sharks because of their appearance and the shape of their dorsal fin.

These "sharks" require large tanks because of their potential adult size of 13 inches and because this fish does better when kept in groups. They are mostly peaceful but may eat smaller fish such as neon tetras when they reach a large enough size.

Also, be warned that these "sharks" are excellent jumpers. Have a hood on your aquarium to prevent your Silver Shark from leaping to its death. They are very fast swimmers and will dart around your aquarium very quickly. Be sure you don't have any sharp objects in your aquarium that could injure your fish.

They are not recommended for the beginner because of their large aquarium requirements.

These freshwater fish (not really sharks) will eat most types of fish food including vitamin enriched flake foods, pellets, frozen, freeze dried and definitely live foods with the key being a varied diet. They sometimes make a clicking noise while eating.
