Tropical Fish And Aquariums



Tropical Fish And Aquariums 

 




The hobby of aquarium keeping and tropic fish as pets is fairly later in the Western World, and took some time to catch on. The keeping of fish in small indoor tanks was only seriously considered in the middle of the last century, when both in Britain and the rest of Europe a considerable interest in the subject developed...

Toward the beginning of the 1900's aquarists around the world started to keep tropical fishes, and it was the "trend" of so doing that started another wave of popular fish culture (keeping fish as pets)...

The older aquarists were obsessed with duplicating nature in their tanks—or rather with the endeavor to attempt to duplicate nature—whereas the keepers of warm-water fishes needed to experiment and make suitable environments for them...

Frequently they started only with the knowledge that the fish must be kept warm, and this in itself raised problems, including the death of most loved weeds and water snails at higher temperatures...

So the aquarium progressively came to be regarded as most of us

see it today, as a beautiful display, not a mirror held up to nature...

In any case, until the keeping of tropical fish, it seems that aquarists in general believed that the proper aim of an aquarium guardian was to reproduce a segment of nature...

They now understand that their task is the maintenance of a profoundly artificial and restricted network of animals and plants, with a balance that can easily topple with disastrous results to probably some of the members. At the same time, aquariums can generally be easily kept up as long as a couple of fundamental facts are perceived and applied with commonsense to the problems that arise...





So lets talk now about some of the characteristics of aquariums and tropical fish...

The old fashioned fish bowl has almost totallytraded for serious fish-keeping by the rectangular glass tank, either made completely of glass or with a metal casing and glass sides and a bottom of glass, slate, or other inflexible material...


Except when used for spawning, for exhibition purposes, or as a hospital tank for the treatment of disease, the tank contains developing, rooted plants; these are set in a sand or gravel layer 1 or 2 inches thick. There might be ornamental rocks, however the main enhancement is usually the plants themselves, which contribute more to the attractive appearance of an all around set-up tank than do the fishes...

Rectangular tanks are usually somewhere in the range of 5 and 25 gallons in limit; a 15-gallon tank measures 24 X 12 X 12 inches and is a most loved size. Smaller tanks than these can't house many fish or permit proper improvement of the plants...

Larger tanks are extremely attractive and give scope for beautiful planting arrangements and for fine development of the fishes, yet they are expensive and not likely to become generally popular. Most fish lovers therefore prefer a scope of medium tanks instead of a couple of exceptionally large ones, however it must be emphasized that fine fishes can be grown in large tanks...

In general, tropical fishes can be housed in smaller tanks than cold-water fishes. This is because they are usually smaller and are also better ready to withstand an overall deficiency of oxygen in the water...

Size for size, most tropical fishes can be crowded a good bargain more than the normal goldfish and particularly more than extravagant varieties of goldfish. A 15-gallon tank may comfortably contain twelve 3-inch rosy barbs, four or five 3-inch regular goldfish and no more, and not in excess of a pair of Orandas of the same size...

Fish consume solid food and excrete solid feces. They breathe oxygen and exhale carbon dioxide, and therefore they tend to deplete their condition of oxygen and to pollute it with carbon dioxide and excrement...

Plants also breathe oxygen, however in sufficiently brilliant light they assembling sugars, and so forth., from carbon dioxide taken from their surroundings, whether air or water, and they release oxygen. This is done in the green leaf...

Plants also absorb dissolved salts and use these together with carbon dioxide in building up complex organic compounds. Not very many higher plants can use solid or complex substances, and before animal excrement (usually known as "mulm" in the fish tank) is accessible to them it must be broken somewhere near growths or bacteria and made soluble...

So plants, in adequate light, tend to restore oxygen to the earth and to evacuate the waste products of animals. In poor light or in darkness they deplete the water or air of oxygen just as animals do. It is only in the daytime, or under splendid artificial light, that they perform the integral function to animals...

From these facts developed the concept of a balanced aquarium, with the waste products of the fishes absorbed by the plants, and the oxygen necessary for the fishes given by the action of the plants in light...

The moral of the story? A well-planted tank with adequate illumination will usually stay clear and sweet for months or years with little attention...

Ideally this article has given you an incredible insight into tropical fish as pets and the healthy keeping of aquariums.
