If I went and bought a Betta fish what is exactly everything that I would need to care for the Betta fish? Right now I have an old Topfin Aquascene 2 tank that I found in my house. It has a hooded light fixture designed to UL and CSA specifications with a 15 Watt bulb. It also has a Aquarium Air Pump (A powerful, yet quiet air pump that will provide oxygen to the fish and provide water motion through the filter system to help keep the water clear and healthy for your fish) <<description on box. It is a 1.66 gallon crystal acrylic tank. It has a Undergravel filter system ( A filtering system designed Especially for the Top Fin Aquarium. Includes A Bottom Plate, Air Stone and Riser Tube. It Is Designed To Pull Waste and Debris To The Bottom Of The Tank To Kepp The Water Clear and Cut Down On Maintenance.)<<description on box
Can somebody please tell me everything else that I will need?
