For the safety of our animals, we only ship live fish, crabs, and select other inverts exclusively via UPS 1 Day Air.  If your order contains this item, you will only see UPS 1 Day Air as a shipping option during checkout. If other items are in your cart that can ship with  2 day or standard shipping options the only shipping method you can still select is UPS 1 Day Air. 

UPS 1 Day is a description of the duration of time a shipment will spend in transit once it has been shipped. This does not guarantee the package will be shipped the same or next day from which the order was placed.

Shipping Schedule for this service

UPS 1 Day: Monday through Thursday

Current Handling Time:

1-9 business days

Here at Aquatic Arts, we consider the welfare of the live animals we are shipping to be of the foremost importance. This process is much more involved than simply creating a shipping label and affixing it to a box. Depending on the order, it takes from 4 to 7 people to complete this process properly. We check the weather conditions here where they fly out of the Indianapolis UPS facility and the destination for each shipment. We start early each morning and go through a multi-step process to have the day's shipments prepared in time for the UPS pickup. The volume of orders in our system also affects the processing time. Therefore our stated handling time is 1-9 business days. 

Shipping Rate

Pricing is by size of package needed to fill entire order and distance it must travel. It will be calculated at checkout.
