Key identification features
- Reddish-orange to reddish-brown body densely covered in small, close-set blue spots, each often edged with a thin dark ring
- Elongated, torpedo-shaped body with a rounded to slightly convex tail margin and a moderately pointed snout
- Blue spots continue onto the dorsal, anal, and tail fins, giving an evenly speckled appearance from head to tail
- Grows to about 3 ft (90 cm), among the larger coral groupers commonly seen on reefs, with a strong, muscular build
Common look-alikes
- Blacksaddled coral grouper — shows dark saddle blotches over a paler body in one color phase, or larger, more widely spaced spots
- Squaretail coral grouper — spots are more angular, and the tail is distinctly squared-off rather than rounded
Where you'll see one
Leopard coral grouper patrols clear-water coral reefs across the Indo-Pacific, from shallow reef flats to outer slopes, usually seen singly hovering near coral heads while watching for passing prey, and it is also an important species in the live reef fish trade.
