DOA

Definition

DOA is the standard livestock-shipping term for a specimen that arrives dead or dies within a defined claim window after delivery. Most aquatic vendors offer a 4-hour DOA guarantee starting at carrier-reported delivery time.

Practical use in aquariums

Fast Aquatics standard: 4-hour DOA window with photo evidence required, processed within 24 hours. Climate-aware shipping holds the order if forecasted temperatures at the destination ZIP exceed safe thresholds. Browse Buyer Protection for the full claim process.

How DOA fits the bigger picture

Understanding DOA matters because it's connected to broader husbandry decisions: sourcing decisions echo for years: a hardier captive-bred specimen pays back its premium in lower mortality + faster acclimation.
