Volume is required. Length and width are optional, but they make the size screen more useful.
No account needed
Use the aquarium's actual usable volume where possible. Substrate, hardscape and equipment can reduce the water volume compared with the advertised tank size.
Why do tank dimensions matter?
Two aquariums can hold the same volume while providing very different swimming space. Active fish may need a particular tank length even when total volume is enough.
Does minimum tank size guarantee suitability?
No. Minimum tank size is only one screening factor. Compatibility, adult size, territory, group requirements, filtration and water parameters still need checking.
