Goniistius vestitus
Common on NSW reef dives, this banded morwong shows up year-round in 20-26C water off Australia's southeast coast.
Grows to around 24cm with a deep, laterally flattened body and a distinctive dark band running diagonally across the head through the eye, giving it a crested look. Body colour ranges from pale grey to brown with faint horizontal striping along the flanks. Often seen hovering close to rock or reef structure rather than out in open water, using its blunt snout to pick at the substrate.
Usually spotted cruising low over rocky reef or hovering near ledges and crevices, picking at the bottom for small invertebrates. Not a fish that bolts at the sight of divers; it tends to hold its ground or drift off unhurried, making it an easy one to approach slowly for a photo. Most sightings are during the day on structured reef rather than open sand.
Its diagonal head band is thought to help break up its outline against dappled reef light, a common trick among temperate reef fish that spend a lot of time near rock and kelp.
No clear seasonal pattern shows up in the data, and with a comfortable range of 20.3 to 26.1C this fish is a year-round presence on the reefs it inhabits. Dive it whenever you're in New South Wales or Queensland waters.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
Australia is the place to find this one, with New South Wales the strongest region by a wide margin and Queensland a secondary hotspot. Divers log it most reliably on temperate reef sites along the NSW coast, where it turns up as a common to very common sighting.
Mapping where Crested Morwong is logged…
Australia is by far the best place, especially New South Wales, where it's logged as a common sighting at many reef sites. Queensland also has a solid population, though NSW sites see it more often.
There's no strong seasonal pattern in sightings, so it's considered a year-round fish on the reefs it occupies. Water temperatures on these reefs sit comfortably between 20.3 and 26.1C most of the year, which suits it fine.
Look for a deep-bodied fish around 24cm with a dark diagonal band crossing the head through the eye, plus faint horizontal stripes along a grey-brown body. It's usually seen close to rock or reef structure rather than swimming in open water.
They typically reach around 24cm in length, making them a mid-sized reef fish you'll spot at a glance rather than something you have to search for.
No, they pose no threat to divers and are generally unbothered by a calm, slow approach, making them a relaxed subject for underwater photography.
