How to spot the Addis Butterflyfish when scuba diving
Chaetodon semilarvatus
Found in tropical and subtropical oceans worldwide with approximately 120 species. Highest diversity in the Indo-Pacific region, particularly the Coral Triangle. The Red Sea and Great Barrier Reef are also hotspots. Caribbean and Atlantic have fewer species but distinctive ones.
Present year-round on coral reefs. Diurnal (day-active), making them easily observable during regular day dives. Often seen in pairs, as many species form monogamous bonds.
Tropical and warm subtropical waters, typically 23-30°C (73-86°F).
Ubiquitous on coral reefs worldwide from shallow lagoons to reef slopes down to about 40m (though a few species venture deeper). Often found swimming in open water near coral formations, but typically not far from the reef structure. Many species are coral feeders, so their presence can indicate reef health. Their bright patterns make them relatively easy to spot. Highest diversity sites include Raja Ampat (Indonesia), Palau, Philippines, Papua New Guinea, and the Great Barrier Reef. Caribbean sites host distinctive species like the Foureye and Banded butterflyfish.
