It seems that the aquarium does not need to choose, it's enough just to buy the model you like. But the professionals talk about a few mistakes that are most often admitted when buying an aquarium.
How to choose an aquarium without errors?
Error 1. Wrong aquarium selection by purpose
Aquariums are divided into spawning, vyrostnye, quarantine and decorative. Which aquarium to choose?
Small aquariums with low walls and a large bottom area are designed for breeding fish. These spawning aquariums. They create special conditions for the reproduction of fish.
Spacious aquariums with low sides (up to 20 cm in height) are designed for growing young fry, and not for the dwelling of adults. Such aquariums are called vyrostnymi.
Quarantine aquariums may differ in size, but their purpose is to isolate diseased fish.
The aquariums described above are mainly used by experienced aquarists and fish breeders, such aquariums are not used for home keeping fish.
To build fish at home you should choose decorative aquariums. They can be frameless (that is, seamless, without joints and using a metal frame) and skeleton, of different size and shape. Frame aquariums are usually rectangular, with a frame of metal. Frameless aquariums are usually round in shape.
Error 2. Selecting an inappropriate aquarium
How to choose the volume of the aquarium? Small is considered an aquarium up to 25 liters, large - more than 100 liters.
In choosing an aquarium it is necessary to focus on the species of fish that are planned to be populated there. Some fish prefer to live in the middle water layer, some prefer to be closer to the bottom or even burrow into the sand. Active fish, even small ones, have to move a lot, so a large territory is also important for them.
But for small fish a small aquarium can become a problem. The death of a single fish in a large aquarium will not bring any particular harm to other inhabitants. In a small aquarium, the death of even one fish can significantly affect the health of other fish.
Another disadvantage of a small aquarium is that it needs to be cleaned more often, since the water in it is more quickly contaminated with fish waste. In general, caring for a small aquarium is much more difficult than for a large one.
Before choosing a large or small aquarium, remember also that in a large aquarium the difference in conditions, in the temperature of the water and its contamination, while parameters of the small aquarium is regularly monitored, is smoothed out.
Conclusion: for active and large fish, only a large aquarium is suitable. For a small number of fish, calm in nature and inactive, you can choose a small aquarium.
Error 3: Unsuitable form of aquarium
No wonder in the popular cartoon "Tom and Jerry" in a small round aquarium lived just one small and very quiet
The most important thing is that the fish in the round aquarium develop a lupus. Therefore, experts advise to place in such an aquarium guppies - they are quite calm. Tips to keep goldfish in a round aquarium are not very appropriate, since these fish are very active and love to play with stones, they will have little round space.
