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.

Price history

The market median for Arrow Crab has changed 10 times in 55 days of tracking. Median shifts here usually come from vendor promotion events or the in-stock mix changing rather than gradual drift (how these prices actually behave) — genuine repricings land on the price drops page as we observe them.
