Home Aquariums and Fish Tanks
Ever since the times of Nezha (Taoist protection deity), during the Shang Dynasty, have men been fascinated by the life aquatic. However, not every one can lead the life of a regular Jacques Costeau, so what most people do is get an aquarium, and bring a bit of Nezha to their homes or offices. Here, you can learn more about aquariums and fish tanks, and the most appropriate fish for aquariums. An Aquarium tank can range from a bowl with its proverbial gold fish, to large public aquariums, which are sort of aquatic zoos and contain the type of aquarium tank that is too big to be kept at a particular house, but they also have smaller tanks.
An aquarium is usually made from one of two materials, glass or acrylic plastic. Glass tanks are generally more affordable, but while they are resistant to scratches, they are not as crack resistant as their acrylic counterparts, and are also much heavier. Acrylic aquariums are stronger and lighter, and can be customized in several different shapes. On the other hand, glass does not require as much maintenance as acrylic does. Regardless of the material, most tanks include a filtration system, an artificial lighting system, and a thermostat.
Back to the topic of maintenance, this refers not only to the physical installation, but also to the well-being of the inhabitants. This includes periodically checking on your little aquatic pets for signs of sickness and stress. Larger aquarium fish tanks require less attention, since the greater volume of water would reduce the impact that a systemic shock, like say, the death of one fish, would have on the equilibrium of the tank. Another factor that can have an influence on the life of the tank is the substrate, or material kept at the bottom, gravel for example. The choice of substrate depends on the type of aquarium, mainly if the water is fresh or salt water.
Salinity will be present in all water conditions, in different levels. Fresh water has a very low salt content that emulates the conditions of a river or lake; brackish water lies in between fresh and salt, like and estuary; and salt water will recall the environment of the sea. The temperature of the water also plays a part in the welfare of the fish, and it has to accommodate the natural environment of the species, whether it is cold water or tropical water.
The type of water will of course determine the type of fish that can live in it. Freshwater species include reedfish, catfish, tetras, hatchet fish and barbs, it is also good for zebrafish husbandry; brackish water is suitable for pufferfish, gobies, and others; and seawater can hold angelfish, bass, batfish, blennies, boxfish, among many others aquarium fish species.
