AquaTec offers a 48-hour guarantee for coral, and alive arrival guarantee on fish. As much as we try to improve our shipping procedures, there will always be some fish and corals that do not survive the shipping process. Shipping is possibly the most stressful event an animal can experience, and certain fish and corals are more sensitive than others. We require a photograph of the DOA fish in the unopened shipping bag in order to process a refund. We require a photograph of the coral if DOA or if it expires within the 48-hour guarantee period.
