An aquarist looking to add tank mates for his betta will need to add some additional filtration equipment. A filter that hangs on the back of aquarium is recommended for betta tank and a lid or top may be required for betta aquarium tank. Betta aquarists should ensure that the gravel used has no sharp edges that can cut and injure fish. The real purpose of an aquarium heater is to keep the water warm and at a constant temperature. Some recommended recommendations for a betta tank are plants, castles as well as other ornaments.
Although the natural habitat of betta is shallow tropical water, they will survive well in even puddles and glass bowls. Even people who keep betta ornamental fish in small tanks rarely provide filtration or heated water. Cool temperature and dirty water will cause heavy amount of stress for betta housed in home aquarium. Poor water conditions may lead to fin deterioration, infection and premature death of betta fish. Fish tanks with filtration are able to establish themselves as a tiny ecosystem and colonies of microorganisms developed in the tank assist in breaking down the waste caused by the fish. About thirty percent of frequent water change is needed in a betta tank along with vacuuming the gravel.
