Clams are not suitable for breeding in aquariums. Clams live primarily in muddy, sandy, or gravelly substrates in shallow waters such as beaches and estuaries. They need seawater and suitable sediment to survive. Even freshwater clams need clean running water and bait to survive. If you put clams in an aquarium, it will be difficult to maintain their health and survival because the body of water and substrate are not suitable for them. At the same time, clams have no ornamental value, so it is not recommended to keep them in aquariums. If you want to observe marine life similar to shells, you can choose shells, starfish, sea anemones, corals and other marine life suitable for aquarium cultivation.
Actually, the method with which you put a piece of fish is feasible, but the chdare you put is false. Putting in things like dead fish and shrimp simply serves to speed up the nitrification process. Novices still don't recommend putting them on. You can simply add nitrifying bacteria. What is called raising fish first, breeding water, should actually be called raising fish first, breeding bacteria. . . . The reason why the ocean can digest the excrement of all living things and turn wastewater into clean water is that there are as many beneficial bacteria living in the ocean as the number of sands in the Ganges. They eat the dirt dissolved in the water and transform. toxins into harmless substances linked to living beings. In the aquarium, we want to imitate this ecosystem which is also the N-Cycle (nitrogen cycle) that novices often hear. In the ammonia cycle process, nitrifying bacteria play a very important role.mimportant. They are generally divided into two types of nitrifying bacteria: aerobic bacteria and anaerobic bacteria, as their name suggests, are bacteria that “love” oxygen. in the oxygen "breathing" environment, it can "eat" NH4 and NO2, transform it into energy for survival, and finally "excrete" NO3. Therefore, even if there is a large amount of NH4 or NO2, in an environment without oxygen, aerobic bacteria will "suffocate" and will not be able to survive in the same way, although there is a large amount of oxygen provided, there is no “food” such as; NH4 or NO2, and aerobic bacteria. Anaerobic bacteria cannot survive either. They need food just like aerobic bacteria. However, the “food” of anaerobic bacteria is NO3 and its “excretion” is N2. During the entire process, anaerobic bacteria do not need to "breathe» oxygen. Apparently, the living conditions of anaerobic bacteria are simpler than those of aerobic bacteria. However, in fact, it is much more difficult to breed anaerobic bacteria in an aquarium than to breed aerobic bacteria... When there is sufficient oxygen, NH4/NO2 In the presence of aerobic bacteria, aerobic bacteria will will develop rapidly. In a closed aquarium, both of these conditions can be easily met. When a considerable number of aerobic bacteria are grown, NO3 accumulates and the anaerobic bacteria are given the opportunity to reproduce. However, in the limited space of the aquarium, most places are filled with oxygen to ensure the reproduction of aerobic bacteria, and the places that provide parasitic nitrifying bacteria are also occupied by aerobic bacteria. day after day, and it is dissolved in water. The amount of NH4/NO2 in water increasesalso. In this case, the rate of reproduction of the aerobic bacteria increases and there is simply not enough room for the anaerobic bacteria to reproduce in sufficient numbers to decompose. the enormous amount of NO3. Therefore, a high NO3 value is a common situation once the aquarium has stabilized.
