熱帯魚・鑑賞魚とは？
熱帯魚・観賞魚とは、人間に憩いを与えるために、水槽や庭に設けた池などでペットとして飼育される魚類の総称です。魚は水域で採集すれば入手できますが、居住域以外の魚を入手するには観賞魚専門店やペットショップの観賞魚コーナーで購入する必要があります。食用に古くから漁獲され、また養殖されてきた魚の美麗な変異個体を選抜したものに金魚や錦鯉があり、また熱帯地方には多種多彩な観賞価値の高い美麗であったり珍奇な形態をした魚が多く、熱帯魚の呼称で古くから観賞魚の主要なジャンルを構成してきました。大きく淡水魚と海水魚に分けられますが、海水魚の方が飼育が難しいようです。また、淡水魚でも人工的に作られた金魚・錦鯉などは野生種と区別されます。
The tropical fish is one of the forms of the aquarium fish. It lives originally in a tropical region, and fishes that breed to the appreciation purpose are indicated. And, the act of breeding those fishes by the appreciation purpose might be only cal led a tropical fish. There is an example of calling fishes that live in regions other than a tropical region from the expansion of the range so, too. As for breeding in Japan that is the temperate zone because of breeding of fishes in a tropical region it in outdoor, most uncommonly becomes indoor breeding.
The tropical fish was originally a word that indicated fishes that became the hobby and the object that bred beautiful fishes that lived in the freshwater environment in a tropical region such as South America, Southeast Asia, and Africa and praiseworthy fishes. However, the example that deviates from an original meaning since the object spreads gradually has increased through the technological improvement and the spread, etc. done by it. It is not a little to indicate all things to exclude fishes that belong to a constant genre like the goldfish and Japanese variety of cyprinodont, etc. of fishes for the indoor appreciation today either. That is, the tropical fish is a common use word that shows the indoor appreciation fish so-called general, and all are not tropical origins. It might be called, the one to live in the low-wash temperature such as the sturgeons is "Tropical fish" when it is extreme.
This is shape the name as a result of the spread by the technical improvement some day swallowed by the tropical fish though breeding of the sea fish was greatly high the hurdle compared with breeding of ..old.. freshwater fish, and originally acknowledged to be a quite different genre. A present tropical fish divides into the sea fish and the estuarine water fish in the freshwater fish and the mouth of a river, etc. if it classifies it according to the water quality of the habitat. However, the estuarine water fish is often treated as a freshwater fish.
Fishes alone do not necessarily limit it, and in addition, the object of breeding is reptiles, is an axolotl of the turtle etc. , and is small aquatic in case of "The tropical fish is done", that is, amphibians such as [tsumegaeru]. When the cnidarian of the crustacean of a medium vertebrate, the prawn, and the crab, etc. , sea anemones, the corals, and medusas, etc. , it is molluscous of the cowfish etc. , and an aquatic invertebrate of various taxonomical groups is contained additionally, and does only the water plant cultivation only, it is said by the third party like "That person is doing the tropical fish".
アクアリウムとは？
アクアリウムとは、水生生物の飼育設備を指します。水族館のような大型施設から小規模の個人的設備があります。今日の日本ではその中でも特に観賞用に熱帯魚（観賞魚）や水草などを飼育・栽培すること、またはそのために構築された水槽を含む環境を指すことをアクアリウムとよんでいます。この愛好者はアクアリストと呼ばれています。
アクアリウムは、世界に約6500万人の熱心な愛好者がいる、世界的に人気のある趣味。1850年代には既に現代のアクアリウムの原型が斬新な珍奇物として初めて開発されていたのだが、後にアクアリウムの魚を健康に保つためのろ過システムを備えたことにより精巧なシステムが開発されるとともに、アクアリウム保有者の数は増大しました。
アクアリウムは、今や、単純な器に一匹の魚を収容するものから、注意深く設計された支援システムを備え複雑に設計された生態系までに及び、飼育条件によって各々に幅広い愛好者層が存在します。これらは、通常は淡水か塩水か、場合によっては汽水域を再現する様式があり、その一方で熱帯温度か冷水温度かによって分類されます。また魚によっては好む硬度も異なるため、飼育する魚の健康維持には様々な水質を再現する必要があります。これらの特性によって、そのアクアリウムで生き残り成長することができる魚等のタイプが決まるが、そのいずれかのジャンルに傾倒するだけでも、かなり広い守備範囲を持つこととなります。アクアリウムに入れる生き物はしばしば野生のものから集められるが、商業ルートに供給できるように自然環境にあるものを捕獲・育成された生物もこれに加えられることも多くなっています。
Aquarium indicates the breeding equipment of the aquatic life. It is a concept across the whole from large-scale facilities like the aquarium to small-scale personal equipment. The environment including the water tank that breeds especially especially, grows the tropical fish and the water plant, etc. that in Japan of today for appreciation or is constructed for that is often indicated. This lover is called an aquarist.
It is the one to reproduce natural environment especially by making a small tropical fish and the mind harmony [maseru] water plant with a beautiful externals grow thickly in the water tank in this feeding procedure for appreciation. There is a lover who consists of the dilettante from of old in Europe and America though this style with the thing that is called "Underwater bonsai", too was seen also in the aquarium to show the underwater creature that exists old in the environment of nature to live in some lovers.
It is possible to maintain it enough even by about one two maintenance with [**] food of 1 and about two times in the water tank that is ideally set with room comparatively every month every day. In addition, apparatus that presses the labor saving said that lighting [**esa] and the lighting can be automated with the timer etc. advances, and there are busy businessman and a person who enthuses about this in recent years. Especially, it prepares for the room for the tropical fish, and it exists to the example of establishing a private aquarium when becoming ardent. 1/4-1/3 of whole water tank glass of water is exchanged at the frequency 1-about twice a week in a standard to some degree water tank though the water substitution frequency changes depending on the amount of capacity and the bred fish and the amounts etc. of the kind and the given food.
To bring it close to natural environment or more besides the fish and the water plant, the crustacean and shellfishes (It is called [tankumeito] from the aim of coexistence with the fish) might be introduced into these.
