Aquarium

Contributing to the solution of complex and versatile tasks, the aquarium must meet certain requirements, be convenient for its inhabitants, observation and systematic maintenance, have the most acceptable design solution and fit well into the interior of the room.

Produced by industry in large quantities aquariums with a capacity of 20-40 liters are suitable for keeping only a few fish and are mainly intended for beginners, small corners of wildlife, or are used as auxiliary containers for breeding fish. For decorative purposes, as well as for the maintenance of collections of rare species of fish and their breeding, more spacious aquariums are used. According to capacity, they are divided into three main groups: small — from 20 to 50 liters, medium — up to 200 liters and large — over this volume. The size of Amateur aquariums should be dictated by home conditions and not go beyond the possible. Amateur aquariums, mostly the result of search and painstaking work of aquarists themselves, abound in many different shapes and designs.

The most convenient and widely used aquariums are rectangular, but you can meet and triangular, hexagonal, octagonal, cylindrical, spherical, lens, as well as wall-mounted watercolors. The ratio of length, width and height of rectangular aquariums is not limited by any norms, but there are limits developed by practice, deviation from which can lead to distortion of the appearance of the aquarium, violation of the biological state in it and inconvenience of its maintenance. For example, in an excessively inflated and narrowed aquarium, the gas exchange regime and the uniformity of heat distribution throughout the water volume will be violated, as well as there will be weak illumination of the bottom part. So unnecessarily high and narrow aquariums, so-called screens, in the last time meet ostentatious. Practical rectangular aquariums with a length of 2-3 times the height and width-not less than 3/4 and not more than the full height. So, the aquarium on 140 l can have the sizes 100X35X40 see the extended rectangular aquariums are effective in exhibition expositions for display of gregarious and mobile fishes. Wide aquariums are convenient for circular or three-way viewing.

Three-walled aquariums, having a rectangular triangle shape in plan, are made when, according to the interior conditions, the most suitable place for its installation is in the corner of the room. Six – and octagonal aquariums are convenient for all-round visibility and a small footprint. Installed on special columns with a stone slide and a flower bed at the base, they are a wonderful decorative decoration of the foyer, hall of hotels, recreation facilities at enterprises, medical institutions, etc.

Cylindrical aquariums (round glass jars 25-30 l) are used for small corners of wildlife and as jigs for spawning and fry.

Spherical and lenticular aquariums are also small. They are installed in the most convenient place in the room, sometimes combining with a floor lamp or furniture. These aquariums are not without drawbacks — they are inconvenient to clean, arrange heating and lighting, fish when moving look distorted in them. However, they are readily available and have mass consumption.

Aquacartins are hinged vessels, the front glass of which has a slight slope and is framed by a frame. They, of course, can not be large capacity, their spawning is difficult, but such aquariums are popular.
