Our Live Arrival Guarantee would cover that. As long as the number of species that we shipped and arrived alive are less than the number you ordered. Our customer have to pay for the shipping of the replacement. sometimes, It doesn't make sense to send a replacement for the dead on arrival fish due to the high shipping cost. We are more than happy to send your replacement order combine with your future order. If you do not know when you will place a future order or do not plan to order from us again, and depending on availability of stock we will submit a refund to your original payment for the Dead on Arrival. Please allow 5 to 10 business days to see the refund reflected on to your original payment methods
