Fish Bowl on Moore Reef is a small-group day-boat site described by Diveplanit, and it should not be confused with the famous Fish Bowl on Hastings Reef, a separate site with its own entry. At Moore the Fish Bowl is a cluster of four bommies positioned at the edge of a shallow coral reef, which gives a dive with plenty of variation in depth: reef fish crowd the first 5 m of water over the reef edge, while around the deeper bommies, at about 18 m, reef sharks are regularly seen. Diveplanit gives Moore Reef depths from 5 m to a maximum of 25 m, typically around 15 m, describes the terrain as straightforward and easy to navigate, with staghorn coral on the upper sections, branching corals and sandy bottom areas, and says visibility is generally clear.

Its list of marine life for the site and its neighbour, 360, includes whitetip reef sharks, green turtles, giant clams, parrotfish, Spanish flag snapper, pufferfish, groupers, barracuda, sweetlips and feather stars. The four bommies make a natural circuit, and there is enough relief to keep experienced divers interested while the shallow edge suits beginners and snorkellers. Diveplanit mentions the MV Reefkist in connection with the site; smaller day boats like this tend to use the less-crowded moorings on Moore rather than the pontoon areas.

Around 300 m to the south-west, the site called 360 is a long sloping reef descending to about 25 m. It is a good option for a relaxed first dive of the day.

Boat access only. Cairns day boats leave from the Reef Fleet Terminal (1 Spence Street) and the neighbouring Marlin Marina on the city waterfront, with check-in between about 7:00 and 8:00 am; most operators run transfers from city and northern-beaches accommodation, and there is paid parking near the terminal. The run of about 47 km out through Trinity Inlet and across the lagoon to Moore Reef takes around 90 minutes on a fast catamaran and noticeably longer on slower dive boats or into a south-easterly chop.

Diveplanit describes Fish Bowl and the neighbouring '360' as sites used by the MV Reefkist day boat; other small day boats may also use them. Enter from the stern platform.

The prevailing south-east trade winds (typically 15-25 knots from April to September) are what limit Cairns outer-reef diving: above about 25 knots trips may be cancelled, and exposed eastern moorings are used only in light winds. Summer northerlies are gentler but make north-facing moorings choppy. Box jellyfish and Irukandji are present from about November to May (stinger suits on every dive), and the cyclone season runs November to April, when a system in the Coral Sea can close the reef for days.

Visibility drops after heavy rain and strong winds; spring is usually calmest and clearest. Moore's horseshoe shape shelters its western side in south-easterlies, so the pontoons run in most weather short of a gale or cyclone. Fish Bowl sits at the edge of a shallow reef and is sheltered in normal trade winds.

Descend beside the first bommie and work around all four, dropping to about 18 m on the deepest where reef sharks are usually seen. Rise into the first 5 m of the reef edge for the return, where reef fish are thickest, and do the safety stop there.

Reefkist (small-group day boat) – regular; occasional use by other Cairns day boats; Moore is also home to the Sunlover, Reef Magic and Great Adventures pontoons, and is visited by Passions of Paradise and Pure Snorkelling; the mooring used on any day is chosen by the skipper according to wind, tide and other boats
