Invertebrates span the biggest price gulf on the site: cleanup-crew staples like snails and hermit crabs sell for a few dollars each, while display shrimp, clams, and rarer specimens cost as much as many fish. Most rows are matched to a single species, so the row compares the same animal across vendors; some pages group several related species under one common name, where the comparison is between similar animals rather than one species.

For cheap cleanup-crew items, per-piece price matters less than shipping — a few dollars of snails rarely justifies a shipping fee on its own, so most people add them to a larger order. For pricier inverts, the same advice as fish applies: check the vendor's guarantee terms, since many stores cover inverts differently than fish.
