In line with our dedicated shipping schedule, we cannot guarantee “overnight shipping” immediately after placing your order. Our website may display in stock fish that we actually do not have on hand at that moment in time. This may be attributed to DOA, backorders, and/or other delays in shipping. If you place an order for a fish that is actually out of stock, we will try our best to inform you of possible delays and opportunities for a substitution or refund. The best way to ensure a timely arrival is to contact us BEFORE placing your order. This can be done via email (email@example.com) or via our phone line (858) 987-0309. Please refer to our COVID-19 delivery estimate (7-15 business days).
