Return policy


We offer a 14-day money back return policy on new unused dry (non-perishable) goods purchased directly from PetJellyfishUs and not a third party retailer.

If you are not satisfied with an unused dry good, please return it to us within 14 days of purchase for a refund of the item's purchase price less a 15% restocking fee. PetJellyfish does not accept any returns past 20 days of order date.

* Please note that shipping costs are non-refundable in any instance once the item has shipped. A refund can only be processed back to the original payment method used to make the original purchase. 

Email to obtain return instructions.

PetJellyfishUs issues refunds once the item has been inspected to confirm it is unused and undamaged. Tanks must be in new condition and re-packaged the same way when returning. Items received that are not new will not be issued a refund.

Note: Retailers may have different return policies, which override PetJellyfishUs  return policy. You should contact them if you purchased our products from them.

A tank that has been wet with water is considered used. DO NOT place accessories, like the pump, LED, hydrometer, loose inside the tank. Return received with damage due to incorrect repacking of components will not be issued a refund.

If your package arrives damaged due to shipping, please contact the shipping company with your tracking number to file a damage claim. Please inform us at if you plan on submitting a claim so that we can assist.


PetJellyfishUs guarantees the Jellyfish Aquariums to the original purchaser against defects in components, materials, and workmanship (that occur under normal use) for a period of one year from the date of retail purchase. The warranty is not transferable and is confined to the original retail purchaser only.

Damage to the aquarium acrylic is not included. The warranty does not apply if damages result from misuse, accident, improper installation, lack of reasonable care, or if the product is not purchased from PetJellyfishUs or an authorized dealer, damage due to modification or alteration that is made to the product, wrong circuitry or unspecified electrical input to the pump.

If customer does not want to perform needed repairs and they are covered by the warranty PetJellyfishUs will either repair or replace the product for the customer.

A copy of original purchase receipt and order number are required for return of the defective product. After any repairs/replacement of the unit, this warranty will thereafter continue and remain in force only for the unexpired period of the original purchase warranty.

Moreover, the time taken for repair/replacement and in transit whether under the warranty or otherwise shall not be excluded from the warranty period. All returns must be made in original packaging, including a master carton around the retail carton within the Styrofoam mold.
