Round aquariums bring unique cosiness to the house and miraculously complement any interior. However, such containers have their own peculiarities and problems: the walls distort the fish; it is extremely difficult to maintain such an aquarium. The optimal filtration system is quite difficult to choose, and even a simple wall cleaning procedure often causes difficulties. Most aquarium enthusiasts maintain round containers manually and partially change the water several times a day. Some people like to use a bottom or hinged filter for an aquarium. Anyway, round fish houses are not recommended to clutter up the decor and plants.
