Aquarium Maintenance & Fish Care – The EssentialsMarch 27 2017
Aquarium owners who have had problems in keeping fish alive for weeks and even some months are always shocked to know that the normal lifespan of the typical aquarium fish is measured not in months but in years.
Although it may vary from species to species, an aquarium fish should be able to have a life of anywhere from 3 to 7 years, or longer. Goldfish can live for as many as 20 years or even more.
Another surprising fact for most is that a fish can actually live healthier and longer lives and sometimes even be able to grow larger in an aquarium than they would do in the wild. In nature, food supplies for the fishes can be variable with the unusual weather patterns and the changing of the seasons. There may be limited amount of food, and it may often demand a lot of energy to find enough food to survive. The wild predators, such as other fish, will make sure that almost all of the young ones of any species do not attain adulthood. Just a few fish get to reach their full lifespan. Fish which are too slow or are weak will sooner rather than later end up being someone’s dinner. Although an aquarium has its own limitations, it can provide an environment where fish thrive and are able to flourish.
Some very basic aquarium maintenance that you have to do to keep healthy fish is directly proportional to how closely you will be following the three essential rules of fish keeping.
If the tank has become overcrowded, if you are consistently feeding the fish too much of food, and if you hardly ever do partial water changes, the filter system will not be able to keep the water quality you should keep. If you do find yourself having to deal with dying and diseased fish on a consistent basis, you are almost certainly doing at least one of these three basic things wrong.
Basic aquarium maintenance is not very time consuming if the tank is set up properly and you go about doing things carefully and correctly. You should form a habit of looking at the fish very closely every other day or daily, as well as checking the temperature of the water.
At least once each week, you should be cleaning the inside of the front glass of the tank and if possible even the side glass, change at least 10 to 15 percent of the water inside the tank, and finally clean the outside of the glass. If the tank has not been congested and you are careful that you do not overfeed, this part of the basic maintenance of your aquarium can even be done every other week. A spacious aquarium also means that a more extensive maintenance, especially on the filter, need not be done very often either. If your aquarium houses some large fish who consume larger amounts of food and hence produce more waste, then you should ideally change as much as 30 to 50 percent of the water every time. Note that the size of the tank also matters. Not only do the tanks of larger size provide a much more stable aquatic environment for the fish, but they also require much less work than the smaller aquariums.
