Lutjanus biguttatus
Small striped snapper found year-round on reefs in Sabah, the Visayas and Koh Lipe, usually in warm water around 27-29C.
A small, slender snapper reaching about 17 cm, easy to pick out by the two bold dark stripes running along a yellowish-white body from nose to tail. Look for the pair of pale spots along the upper back that give the species its name, usually sitting between the dorsal fin and the lateral line. It has the classic snapper profile: a sloped forehead and a slightly forked tail, but its small size and slim build set it apart from bulkier reef snappers.
Usually seen hovering in small, loose groups just above the reef structure, often tucked near coral heads, ledges or rubble patches where it can duck for cover. Divers tend to log it as uncommon rather than abundant at most sites, so a sighting often means checking sheltered reef faces rather than open water. It is not particularly shy but keeps a bit of distance, drifting back into structure if you approach too directly.
Its two pale back spots are a real field mark among snappers, letting divers separate it at a glance from the many similarly striped reef species it shares habitat with.
No clear seasonal pattern shows up in the data, and its comfort range of roughly 27.5 to 29.2C matches tropical reefs all year, so it is a reasonable year-round sighting anywhere in its range.

Most reliably logged in Southeast Asia, with strong numbers across Sabah in Malaysia, the Visayas in the Philippines, and Thailand's Koh Lipe, Koh Phi Phi, Phuket and Khao Lak. It also turns up well in Indonesia's Raja Ampat and the Maldives' Central Atolls, making it a fixture of Indo-Pacific reef dives generally.
Mapping where Twospot Banded Snapper is logged…
Best chances are in Sabah, Malaysia, the Visayas in the Philippines, and Thailand's Koh Lipe and Koh Phi Phi. It is also logged in Raja Ampat, Indonesia and the Central Atolls of the Maldives.
There is no strong seasonal pattern in sightings, and its warm-water niche of about 27.5 to 29.2C is present on tropical reefs year-round, so any time of year works.
Look for a small, slim snapper around 17 cm with two dark horizontal stripes running the length of its body and a pair of pale spots on the upper back near the dorsal fin. It usually hovers near reef structure rather than out in open water.
They are a small reef snapper, typically reaching around 17 cm, so they are easy to overlook among larger reef fish.
No, they pose no danger to divers. They are small, reef-associated carnivores that keep their distance and have no history of aggressive behaviour toward divers.
