Acanthopagrus bifasciatus
Silvery reef fish with two dark bars, logged year-round on Red Sea reefs in South Sinai and Marsa Alam at 25 to 29 C.
A silvery, deep-bodied fish around 25 cm with a steep forehead and two dark vertical bars, one crossing the head behind the eye and one at the base of the tail. The body flashes pale gold or bronze along the flanks in open water, fading against sand or rubble. Look for the blunt snout and single-coloured dorsal fin rather than any bold striping along the body, which separates it from the more strongly barred bream species on the same reefs.
Usually seen cruising singly or in loose small groups over reef flats and sandy patches next to coral, picking at the substrate rather than schooling tightly like some of its bream relatives. It keeps a fairly relaxed distance from divers and snorkellers, neither bolting nor approaching, and is most often logged at moderate rather than shallow depths where the reef meets open sand.
Like other Acanthopagrus bream, it has strong, blunt teeth built for crushing shelled prey off the reef and rubble rather than chasing fast-moving fish.
No clear seasonal pattern shows up in the sightings, and with a comfortable range of 25 to 29 C it stays active on these reefs year-round, so any month is workable.

Most reliably found on Red Sea reefs, with the strongest logs from South Sinai and Marsa Alam & the Deep South in Egypt, plus the Red Sea Riviera further north. Oman's Daymaniyat Islands hold a solid population too, and it turns up occasionally off Eilat in Israel at the top of the Gulf of Aqaba.
Mapping where Twobar Seabream is logged…
Egypt's Red Sea is the stronghold, especially South Sinai and Marsa Alam & the Deep South, with more sites along the Red Sea Riviera. Oman's Daymaniyat Islands are a reliable second location, and it is occasionally logged near Eilat in Israel.
There's no strong seasonal pattern in the sighting data, and it tolerates a wide warm range of 25 to 29 C, so it's present on Red Sea and Omani reefs throughout the year.
Check for a silvery, deep-bodied fish around 25 cm with two dark vertical bars, one behind the head and one near the tail base. It lacks the multiple stripes seen on some related bream, making the two-bar pattern the key giveaway.
They typically reach around 25 cm, a modest reef fish size that's easy to overlook against busier, more colourful Red Sea species.
No, they pose no threat to divers and simply carry on foraging over sand and reef when approached calmly.
