Every US state has its own aquatic species list. Some are tightly regulated (Hawaii, California, Florida) and some defer almost entirely to federal Lacey Act enforcement. Federal-only enforcement applies in DC. No additional restricted species list at the District level.
The species below are banned for import, sale, or interstate shipment under the federal Lacey Act. State-level enforcement may be additional, but the federal ban is the floor:
The species below are prohibited from possession, sale, or import in District of Columbia without exception. Most are also banned at the federal level via the Lacey Act, which means the state ban is in addition to federal enforcement. Fast Aquatics blocks these species from checkout when shipping to a District of Columbia address.
District of Columbia does not maintain a separate conditional / permit-required species list at the state level beyond the federal-only restrictions above.
The vast majority of aquarium ornamentals are legal in District of Columbia without permit:
When a buyer enters a District of Columbia shipping address, our state-restriction engine automatically blocks any item from the cart that is banned in District of Columbia. The buyer sees an inline note ("This species cannot ship to District of Columbia") instead of a confusing rejection at payment. Where a permit is required for a conditional species, we route the buyer to the relevant state agency rather than completing the sale.
Vendors selling on Fast Aquatics do not need to memorize 50 states of regulations - the system enforces them automatically. This is one of the reasons Fast Aquatics exists: 50-state shipping is a paperwork problem more than a logistics problem, and we have done the paperwork once so vendors do not have to do it 1,000 times.
The state agency above is the authoritative source for District of Columbia-specific rules. Federal Lacey Act species are listed by the US Fish and Wildlife Service. When in doubt about a species you do not see explicitly listed, contact the state agency directly - rules change and our list is updated periodically but is not a substitute for current state guidance.
