1.	would there be any bacteria inthe aquarium? if yes, then why?
Answer» Yes bacteria do exist in water bodies They are in aquarium as well One of the most important things an aquarium hobbyist can do to maintainwater qualityis seed their aquarium with good bacteria from an established, stable and healthy tank.Good bacteria can come from a handful of populated gravel or substrate, or a used filter pad that’s been rinsed intank water, a usedsponge filter, or even an external filter box itself. Dropping a piece of used filter pad into a new filter box helps establish a colony of good bacteria in a new tank. Growing and maintaining good bacteria is probably the single most important thing an aquarium hobbyist can do to keep a healthy tank. Protect good bacteria as if it were gold, and so many of the most common issues may never arise.
