An aquarium fish tank is a glass or acrylic fish tank that’s set up to house either freshwater or saltwater fish. They often have rocks, ocean backgrounds, plants, gravel, pumps, lighting, and heating. All you often need to do is add fish and water.

Every aquarium fish tank is different and has a range of various features. As a result, you should spend a lot of time thinking about what you want in an aquarium, and what your preferred fish breed will need. The more you know about your chosen species of fish, the more familiar you can be with the type of tank you need to house them.
