Fish Tank

One of the most important portions of housing a fish is creating the proper ecosystem for it. It is complicated to try and understand the multiplicity of factors that go into a fish’s environment, but we will try and map them here. For fish you need to understand that you must have an aquarium that sufficiently houses them. A simple starting place is to be sure that the fish can turn around comfortably and can swim within the tank. Too often restaurants and other public locations will house a fish without giving it the space it needs. Just as some public places are not giving sufficient attention to the proportional size of the fish, households do the same thing.

A good rule of thumb for freshwater fish is for every adult inch in length, the fish needs 12 square inches of water surface area. This is an average, but sets the bar for oxygen content in the water. If you’re looking for metric units the measurement is for every four centimeters of length the fish needs four liters of water. This is a reasonable basis, but certain fish consumer more oxygen in the water than others. Saltwater fishes might need more or less, but it is entirely dependent on the fish and their normal habitat. For example warmer water fish consumer more oxygen in the water than colder water fish. This is simply due to their level of activity. Since fish are cold blooded their heart rate and organ workload is designated by the temperature of their surroundings. Although it might not seem this way, fish are incredibly sensitive to water temperature changes because they are so dependent it.

With that in mind it is imperative to have a temperature gauge of some sort. A simply mercury thermometer will work, but it is recommended that it is stainless steel so that the mercury has a very limited chance of leaking. There are digital display version that run on batteries and these are sometimes preferable for their accuracy. Regardless of the monitoring system, you ought to have a heating or cooling element depending on the fish you intend to keep. The decision to heat or cool stems from the specifics of the fish that you intend to keep. Like humans, fish can only live in a specific range so it is important that you’re reading and adjusting the temperature in accordance with the seasons and the average temperature of your household.

A good fish tank usually starts off at least one gallon of water. For a small goldfish or another single animal these are sufficient as long as measures are put into place to filter and aerate the water. The scale of any given fish tank can increase dramatically, but the density of water usually brings some physical limitations. Since water becomes quite heavy, most home aquariums remain under 1 cubic foot of water. Greater than this and customized heavy duty glass panels must be made. For larger public aquariums there are an abundance of ways to be sure that the translucent material does not break. For example, silicone and plastic layers are usually made that can be several inches thick and capable of holding in a wall of water while providing a good viewing area if customized. More and more often tunnels of glass with the top half being see through and the bottom half containing a walkway are becoming more common due to technological innovations in materials and engineering.

A home fish tank will need to incorporate several different factors in order to provide the best possible environment for your fish. Biological and mechanical circulation is usually needed to maintain a specific oxygen content in the water as well as to keep the water clean. With the right measurements a fish tank can be as comfortable as their original breeding waters.
