About Fish Tank Sizes
Free reference tables and calculators for aquarium keepers.
What this site is
Fish Tank Sizes gives the dimensions, weight and stocking limits of the standard aquarium sizes, along with calculators for volume, weight, substrate and stocking. It is published by Evergreen Digital Media LLC.
Where the numbers come from
Tank dimensions are the common outside measurements, and weights are our own estimates from glass thickness, water and substrate. Fish sizes, temperature and tank minimums come from Seriously Fish species profiles, FishBase, Aquarium Co-Op and Ornamental Fish International, and each guide page names its sources. The stocking calculator is our own model and a guide, not a guarantee.
