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. Texas Parks and Wildlife maintains a substantial restricted species list. Suckermouth catfish (plecos) are a major established-invasive concern in Texas waterways. Confirm species before ordering.
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 Texas 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 Texas address.
The species below are not banned outright but require a state permit, aquaculture license, or specific use case (e.g. triploid-only, indoor-only, retail-only). Hobbyists in Texas should confirm with the state agency before ordering any of these.
The vast majority of aquarium ornamentals are legal in Texas without permit:
When a buyer enters a Texas shipping address, our state-restriction engine automatically blocks any item from the cart that is banned in Texas. The buyer sees an inline note ("This species cannot ship to Texas") 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 Texas-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.
