Aquariums are often used to house reptiles of varying sorts. Unfortunately, we don't always know what size tank we have, though we may have the dimensions. To make things easier for our users, we have 2 utilities to help circumvent this problem.

Below we have a listing of the most common aquariums and their dimensions. This can be used as a quick guide for those who have their dimensions handy.

We also have a Gallon Converter. The Gallon Converter allows you to input your tanks dimensions and find out its Gallon equivalent. This can be used to find out exactly how many Gallons your custom enclosures are as well! The Gallon Converter is located here: Gallon Converter
Herp Center also offers a way to calculate the volume found in hexagonal and cyndrical aquariums. You can find it here: Odd Shape Converter
