Responsible fish keeping begins with how you set up your aquarium tank. Choose the aquarium that will comfortably house all the fish that you want. You may have heard some people say that fish will only grow to the size of their tank. This is basically a myth. Before long, you will need to buy a larger aquarium, if you don’t want your fish getting sick or dying on you due to lack of space and oxygen.
Find out as much as you can about the fish that you plan to keep, to know what size of aquarium you need to get for them. It is best to factor in the adult size of the fish when choosing the size of the aquarium. But if you got a small aquarium and later it became too small for your fish, then upgrade as soon as possible to the appropriate size.
Make sure that the fish you choose will be compatible with each other. Responsible fish keepers will not add different species to the same aquarium without first making sure that they will get along. Different fish have different requirements for pH, water temperature, and other measurements, too. Do not purchase too many fish for your tank, either. Just because they are small doesn’t mean that several dozen of them can fit in your small aquarium.
If your fish or aquatic plants become too big for their aquarium, never release them in a pond, stream, or other wild environment. Unfortunately, many people do this when their fish grow much larger than they originally thought they would, and it can wreak havoc on the local ecosystem. If your fish survive, they may begin breeding and eventually kill off native species.
A lot of tropical fish found in the aquarium cannot continue to live outside the aquarium especially in frigid waters. Releasing them in this environment is like giving them a death sentence. If you cannot afford an upgrade of your tank, returning your fish to the pet store is a better alternative.
Besides the aquarium itself, you’ll also need a water filter and a heater. These are necessary for the vast majority of fish that you may want in your aquarium, and it would not be responsible to set up an aquarium without these. The filter type your aquarium requires depends on its size. The heater depends on the type of fish you plan to keep, since different species have varying temperature requirements.
Responsible fish keeping dictates that you regularly change the water in your tank even if you already have a water filter installed. A weekly test of your tank’s water condition is also a must. Check that only acceptable levels of pH, nitrite and ammonia are present.
Some of your fish may be small but that does not mean that you can just disregard them or that they will survive with less care than what you are giving to the other fish. Do not forget to feed your fish. Make sure that they receive proper nutrition. Find out the best kind of food for them.
Responsible fish keeping means making a commitment to keeping their environment as healthy as possible.
