Top 10 Marine Species You Can Spot While Diving in Phu Quoc

Probably the most famous little fish in the ocean! Clownfish live inside sea anemones and are always curious, making them great subjects for photos.
Where we see them: Shallow reefs, especially in the south.

These colorful fish play a huge role in reef health — they literally create sand by eating algae off the coral.
Fun fact: A single parrotfish can produce up to 100 kg of sand per year!

Cute, slow-moving, and extremely photogenic. You’ll often find pufferfish hovering around corals or hiding near small caves.
Remember: They inflate when stressed, so please don’t try to touch them.

Not an everyday sight — but when they appear, it’s magical. Phu Quoc waters are part of their feeding routes.
Best chances: Deeper southern sites and calm morning dives.

Masters of camouflage! They change color and texture in seconds.
Why divers love them: They’re curious and will often come close to inspect you.

Often misunderstood, octopuses are shy but incredibly intelligent.
Where to look: Under rocks, inside holes, or blending perfectly with the reef.
Spotting one is a guaranteed “wow” moment.

Tiny but fascinating. These shrimp run “cleaning stations,” removing parasites from fish.
Tip: Hover calmly — you might get a free manicure!

Similar to pufferfish but with long spines. Their big, round eyes make them look like underwater teddy bears.
We often see them: Cruising around coral blocks or hiding under ledges.

Bright, colorful, and super common — these species bring life to every reef in Phu Quoc.
Why they’re special: They always swim in pairs, making them easy to spot.
