Answer 1

At starting a new aquarium, it is very important to establish a good "bacteria bed" for the nitrification process for best accomplished through the slow introduction of fish. Source of oxygen and a large amount of surface area to house this bacteria must be provided. Filters provide the ideal environment.
Fish waste, food and other decaying organic material break down into an ammonia. Even in low levels, ammonia will increase the breathing rate of fish by irritating gill tissues. Damage to the body tissues of both fish and invertebrates will follow, causing disease and death.
Aerobic bacteria i. e. Nitrosomonas convert ammonia into nitrite, which is also harmful to fish as ammonia .It destroys the hemoglobin in the blood of fish and invertebrates for which blood cannot carry oxygen.
