Richelieu Rock at its finest 🐟

Endless clouds of glassfish drift across the reef, turning the entire dive site into a living, moving wall of silver. These dense schools don’t just create incredible visuals — they’re a sign of rich, nutrient-filled waters and a healthy ecosystem.

Glassfish are small, transparent schooling fish that use strength in numbers for protection — and when they gather like this, the reef truly comes alive.

Where glassfish gather, predators follow. Trevallies, snappers and hunting reef fish weave through the swarm, making every dive dynamic and unpredictable. It’s this constant interaction — small fish, big action — that makes Richelieu Rock one of Thailand’s most iconic dive sites.

Most people overlook the impact of sunscreen on coral reefs… but the research is honestly surprising. 👀🪸

Certain ingredients in chemical sunscreens are illegal in Thailand’s national parks, and
using the wrong one can cost you up to 100,000 THB. 😳

We broke down what the ban means, why it exists, and what the science says in our latest blog. It’s a quick and interesting read — and if you're diving or visiting the Similan islands and other national parks, it’s worth knowing!
