Reading today's numbers
Today's 5 in-stock listings span $74.99 to $274.99 — the high end is 3.7× the low. For fish, a gap like that usually comes from listings at different size classes, or captive-bred versus wild-caught stock, rather than one vendor simply overcharging. The $134.99 median is the fairest single benchmark: half of those listings sit at or below it.

A new fish cares most about being acclimated gradually to your tank's own water rather than dropped straight into it — shipping bag water is best kept out of the tank — and then about being offered food it will actually take. Chewy — a general pet retailer that sells no live coral or marine fish, and is not one of the vendors this index tracks — carries reef salt mixes, saltwater test kits, marine fish food, and coral and invertebrate food.
