Can you put a goldfish in vase?

It is not recommended to keep a goldfish in a vase, as it is not a suitable environment for the fish. Vases are typically small and lack proper filtration, aeration, and heating systems that are essential for the health and well-being of goldfish. Goldfish require a spacious aquarium with at least 20 gallons of water, as well as a filter, heater, and air pump. Without these proper conditions, goldfish may experience health problems, such as stunted growth, fin damage, and increased susceptibility to diseases.
