Listing rules

Keep it legal and keep it honest. Listings that break these rules are removed, and repeat offenders lose their account.

Not allowed

Endangered or protected species

Anything listed under the U.S. Endangered Species Act, or on CITES Appendix I. Appendix II species (many corals, some fish) only with the paperwork the law requires, and only if you can show it on request.

Species that are illegal where you or the buyer live

Federally injurious species (for example snakeheads and invasive carp) and anything your state bans or restricts. California, for example, restricts piranhas, snakeheads and every Caulerpa species. Check your state wildlife or agriculture agency if you're unsure.

Wild-collected animals or plants from local waters

Don't sell what you took from a creek, lake or the ocean unless you hold the licence that allows it.

Getting around the rules

No restricted species as a "free gift" with another item, hidden in a bundle, or described in code words.

Sick, dying or mistreated animals

No livestock you know is sick, diseased or unfit to ship. Say so plainly if something is being treated.

Prescription drugs and banned chemicals

Prescription-only medications, and anything illegal to sell to the public.

Anything misleading or unrelated

Wrong species names, stolen photos, fake prices, and anything that isn't for the aquarium hobby.

Welcome here

Your responsibility

Wildlife law differs by state, and sometimes by county. By posting you confirm you may legally keep, sell and transfer what you list, and that you hold any permit it needs. Buyers are responsible for the rules where they live.

Shipping live animals has its own carrier rules. Check them before you ship.

Never release aquarium animals or plants into the wild. Rehome them instead.
