Live aquatic livestock ships overnight via FedEx Priority Overnight or UPS Next Day Air. Order Monday through Wednesday for delivery by Thursday. Most carriers do not deliver live livestock on weekends, so vendors typically hold Friday-Sunday orders until Monday or Tuesday morning to avoid weekend exposure. Total transit is 18-22 hours from packing to your door.
Overnight shipping is the only acceptable transit time for live aquatic livestock. Anything longer and you start losing animals to oxygen depletion, ammonia buildup in the bag, and temperature stress.
FedEx Priority Overnight delivers Saturday in most major metros but not Sunday. UPS Next Day Air typically only delivers Monday through Friday. A Friday afternoon shipment to a Sunday-only destination spends 60+ hours in a carrier hub - that kills livestock. Most vendors hold Friday-Sunday orders for Monday or Tuesday shipping rather than risk it.
Fast Aquatics holds shipments automatically when forecasted temperatures at the destination ZIP exceed 95F or drop below 32F during the transit window. The buyer can waive the hold if they want to ship anyway, but the climate hold is the cheapest insurance against weather-related DOA.
Overnight delivery, insulated foam-lined boxes, heat or cold packs, oxygen in the bag, and carrier-tracking surcharges add up. A typical box runs $40-65 for FedEx Priority Overnight. Most marketplace vendors set a free-shipping threshold (often $99-149) so customers can stack orders to avoid paying it on small carts.
Some vendors offer local pickup at their facility. Look for the "local pickup available" badge on a vendor profile. For most vendors with no retail storefront, overnight is the only option.
