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.

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.

Price history

The market median for Gem Tang has changed 19 times in 100 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.
