Fish Market is one of several southern Ribbon Reef moorings listed on Mike Ball Dive Expeditions' Cod Hole–Ribbon Reefs itinerary map, alongside Andy's Postcard, Clam Beds, Steve's Bommie, Flare Point, Blue Lagoon and Circle of Life. Mike Ball has explored the Ribbon Reefs for more than 30 years, and its map is the most complete public list of moorings in the area, but not every mooring has a published description, and Fish Market is one of those without one.

The name implies a site where fish gather in numbers, perhaps a bommie or reef corner where schools of fusiliers, snapper, trevally and surgeonfish congregate, or a cleaning station. On the southern Ribbons, comparable sites such as Steve's Bommie and Temple of Doom are known for dense schools of big-eye trevally, snapper, goatfish, fusiliers and barracuda around coral pinnacles, and for reef sharks patrolling at the edges. Those comparisons are indicative only and should not be taken as a description of this site.

General conditions match the rest of the Ribbons: visibility commonly 15–30 m, water of 23–29°C depending on season, and mostly gentle currents on the lagoon side. In June and July dwarf minke whales frequent Ribbon Reef No. 3, close to the southern moorings.

Divers should treat this as an occasional alternative mooring. If it appears on the day's plan, ask the cruise director for the route, depth and what to look for. The record should be updated when a site description becomes available, and divers who log it are encouraged to share depth and species notes.

Liveaboard only (or fly-dive via Lizard Island). Mike Ball Dive Expeditions' Spoilsport and Spirit of Freedom depart Cairns (Trinity Wharf / Marlin Marina) in the evening and steam north overnight, roughly 12–14 hours and 200–250 km, to reach the Ribbon Reefs by morning; some itineraries fly Cairns–Lizard Island (about one hour, scenic flight along the coast) and board or disembark there. Trips run 3–7 nights and include Fish Market occasionally.

Divers enter by giant stride from the dive deck at the mooring and descend the mooring line. It is listed on Mike Ball's itinerary map in the southern group with Andy's Postcard, Clam Beds, Steve's Bommie, Flare Point and Blue Lagoon and is used at the crew's discretion.

The Ribbon Reefs sit on the edge of the continental shelf and take the full south-east trade wind from April to October. Lagoon-side moorings stay diveable in 20–25 knot SE winds, but reef-front sites and passes need lighter winds; liveaboards shelter behind the reefs overnight. September to December is usually calmest.

Tidal flow through the gaps between the Ribbons is strong on springs, so exposed pinnacles are timed for slack water. December to April brings rain, lower visibility and cyclone risk; box jellyfish and Irukandji are possible November to May.

No published dive plan. Expect a moored reef dive: descend the line, follow the crew briefing, turn at half gas and finish with a safety stop on the reef top.
