The importance of stable water quality means that you only should keep sharks in established tanks Food Intake in Fish read pdf

They are known as the seas largest fish with the potential to grow over 60 feet long and weigh over 70,000 pounds. The Whale Shark also has the potential to live to be over 100 years old, but by being endangered, many marine experts wonder if some whale sharks will ever make it to be even half that age. Although various petitions and treaties have been created, and signed, to help save the lives of endangered ocean life it is up to each individual to do their part to aid in saving marine animals in danger , e.g. Cichlids from West Africa
