State aquarium legality laws protect three things: 1) Native ecosystems from invasive species (snakeheads, walking catfish, piranha). 2) Threatened species from over-collection (some seahorses, native trout, sturgeon). 3) Public safety from venomous + parasitic species (electric eels, pufferfish toxins, some tropical worms).
The federal Lacey Act bans interstate shipping of certain species (snakeheads, certain Asian carp). State laws layer on top - California prohibits piranha + walking catfish + gar + mosquitofish. Florida requires permits for stingrays. Hawaii requires permits for any non-native saltwater livestock. Texas and a few states require permits for piranha. Always verify before purchasing.
Fast Aquatics enforces state legality at checkout via a 52-rule database. Restricted items show "not available in your state" + recommend legal alternatives. We also block delivery of prohibited species to addresses where they're banned.
Can I bring my fish when I move states? Generally yes for non-restricted species. For state-prohibited species (e.g., piranha into California), no - and the state can confiscate. Check the destination state laws before moving.
What happens if I order a banned species? Reputable vendors block the order at checkout. If somehow you receive it, the state could confiscate. The species itself is also a risk - some bans exist because the species can establish in local waters and become invasive.
Where can I see the official state laws? Each state's Fish & Wildlife Department publishes the regulations. We link to the official state agency on each state page in our legality directory.
Do federal laws override state laws? Federal Lacey Act bans (snakeheads, certain carp, federal endangered species) apply nationwide regardless of state law. State laws can be more restrictive than federal but not less.
What about fish I caught locally? Some states allow you to keep native fish caught yourself (with a fishing license). Most prohibit transferring caught native species across state lines.
