Scolopsis ghanam
Silvery reef fish with a dark eye-ring, logged at over 100 sites in South Sinai and common year-round in 25-29C Red Sea water.
Looks like a slim, silvery-grey bream around 21 cm with a faint yellowish wash along the upper body and a distinctive dark ring circling the eye, the feature that gives monocle breams their name. The body is elongated and slightly compressed, tapering to a forked tail, and it usually sits just off the reef rather than tight against it. There's no strong sex-based colour difference reported, so what you see at any size is roughly what you get.
Expect to find it cruising alone or in small loose groups over sand patches and reef edges, picking at small invertebrates rather than schooling tightly like some reef fish. It's generally unbothered by divers, holding its distance without bolting, and is most often noticed during the middle of a dive as it works the reef base in shallow to moderate depths rather than up in the water column.
Its dark eye-ring isn't just decorative, it's the quickest way to separate monocle breams from the many similarly silvery reef fish sharing the same sand-and-rubble zones.
There's no detected seasonal pattern, and with a comfortable range of 25.1 to 29.1C it's present on these reefs all year, so any month works for a trip built around it.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
This is very much a Red Sea and western Indian Ocean fish: it's most heavily logged in South Sinai, the Red Sea Riviera, and Marsa Alam in Egypt, with strong secondary populations around Oman's Daymaniyat Islands and Muscat. Divers also report it reliably in Aqaba (Jordan), Zanzibar (Tanzania), Kenya, and the UAE's East Coast.
Mapping where Arabian Monocle Bream is logged…
South Sinai and the Red Sea Riviera in Egypt are the strongest areas, with good numbers also around Marsa Alam, Oman's Daymaniyat Islands and Muscat, Aqaba in Jordan, and Zanzibar in Tanzania.
There's no clear seasonal pattern in sightings, and it tolerates water from about 25 to 29C, so it's a year-round fish on the reefs where it lives.
Look for a silvery-grey, slightly elongated fish around 21 cm long with a dark ring encircling the eye, the clearest field mark for this species. It's usually seen alone or in small groups near the reef base rather than schooling in open water.
They reach around 21 cm in length, a modest, mid-sized reef fish rather than anything dramatic.
No, they're harmless to divers and simply go about feeding near the reef, showing no aggressive or defensive behaviour towards people in the water.
