Morwong fuscus
Common on reefs across New South Wales in 16-25C water, this red-brown reef fish is a year-round sighting for Aussie divers.
Look for a stocky, torpedo-shaped fish around 45cm with a reddish-brown body crossed by pale horizontal stripes running from head to tail. It has a blunt, slightly downturned snout suited to picking food off rock and reef surfaces, and tends to hover close to the bottom rather than swim in open water. The steady striping pattern is the main giveaway compared to other reef fish sharing the same rocky ledges.
Divers most often find these fish tucked close to rocky reef structure, hovering near ledges and crevices rather than out in open water. They're generally unbothered by divers, holding position or moving off at an easy pace instead of bolting, which makes them a fairly relaxed subject to observe or photograph. Look for them working the reef surface as they forage rather than schooling or chasing prey in the water column.
Their blunt snout is built for picking invertebrates directly off rock and reef surfaces rather than chasing prey through open water, which is why they're almost always seen hugging structure.
Sightings are logged year-round with no strong seasonal pattern, and the observed temperature range of 16.4 to 25C spans NSW's cooler winter and warmer summer reef conditions alike. Any time of year you're diving temperate NSW reefs, there's a solid chance of finding one.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
This is very much a New South Wales fish, with by far the strongest and most consistent sightings logged along that coast. Smaller numbers turn up further north into Queensland, but NSW reef and rock-ledge sites are where divers reliably run into it.
Mapping where Red Morwong is logged…
New South Wales is the stronghold, with reef and rocky ledge sites all along that coast producing the most sightings. Smaller numbers are also logged further north in Queensland.
There's no strong season logged, so sightings happen year-round. They're recorded across water temperatures from about 16 to 25C, covering both NSW's cooler and warmer months.
Look for a stocky, reddish-brown fish around 45cm long with pale horizontal stripes running the length of its body. It typically sits close to rocky reef structure rather than swimming in open water, with a blunt snout suited to foraging on the bottom.
They typically reach around 45cm in length, making them one of the larger fish regularly seen hugging rocky reef structure in NSW waters.
No, they're not considered dangerous to divers. They tend to hold their ground or move off calmly rather than react defensively when approached.
