Reading today's numbers
Today's 2 in-stock listings sit in a fairly tight band, from $29.99 to $44.99, so the single vendor listing it prices it consistently, and the $37.49 median is a solid benchmark for its asking price.
Only one of the vendors we track currently lists it, so this range reflects a single store's listings rather than a cross-vendor comparison — worth keeping in mind when judging the price.

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.
