Custom aquariums are available in an enormous range of sizes, from literally a bowl through to commercial aquariums where visitors can walk underneath the aquarium watching the fish pass overhead.

For people who either have a larger disposable income to invest in their aquarium or have specific design needs, such as needing the aquarium to fit into a specific location, then a custom -built aquarium may be the answer.

Custom aquariums are by their very nature more expensive but are built to precisely your individual requirements. There are a number of specialty stores that will make customized aquariums although they are becoming harder and harder to find.
