What is the best shape for a fish tank?

Rectangular fish tanks are best for better water quality and overall fish health. This is due to the larger surface area between air and water, which allows for more efficient gas exchange.

What is the most popular fish tank?

The most popular fish tanks include a Contour Glass Aquarium Kit that we included in this article. The Contour Glass Aquarium Kit has everything you need to get started with your betta tank, and it has a unique design that will show your fish off both day and night.

Which aquarium is better glass or acrylic?

Acrylic is generally the better choice for beginners. The only difference between the two is the weight. The glass aquarium can be as much as 10 to 15 times as heavy as the acrylic aquarium. But glass aquariums are more affordable and scratch resistant.
