Reading today's numbers
Today's 12 in-stock listings span $1.99 to $119.99 — the high end is 60× the low. For invertebrates, a gap like that usually reflects listings at different sizes or grades rather than one vendor simply overcharging. The $11.24 median is the fairest single benchmark: half of those listings sit at or below it.
Keeping it alive once it arrives
Disclosure: the Chewy links below are affiliate links — if you buy through them we earn a commission, at no extra cost to you. This never affects the prices or vendor rankings above. Details.
Invertebrates tolerate swings in salinity and water chemistry worse than most fish do, so consistent mixing and regular testing matter more here than anywhere else in the tank. 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.
