US State Aquarium Species Rules

• Mystery Snail (banned without a permit)

We did not read Alabama's plant list.

The site that publishes Arizona's rules refused our automated request, so we could not read the restricted wildlife list.

We did not read a Georgia plant list.

• African Dwarf Frog (banned without a permit)

Hawaii needs an import permit for every animal on its conditionally approved list, which names most aquarium fish families. We have not matched that list species by species, so it is not counted here. We did not read Hawaii's plant list.

Oregon amended its prohibited list in 2025, and this page may not show every change. Oregon also treats species it has not classified as prohibited.
