Meet the Top 10 Tropical Fish of Thailand – Seen Right Here in Pattaya
Dusky Damsel Fish
A bold little reef guardian, the Dusky Damsel Fish is found all over Pattaya’s coral gardens. Known for their territorial nature, they’ll swim right up to divers and snorkelers with zero fear. Don’t be surprised if one gives you a tiny nip, just their way of saying “stay off my turf!”
Copperband Butterflyfish
This delicate beauty is one of the most recognizable tropical fish in Thailand. With vertical orange-yellow stripes and a false eyespot on its dorsal fin, the Copperband Butterflyfish glides gracefully through coral heads and rocky reefs. Often spotted in pairs, they’re a peaceful highlight on any dive.
Six-Banded Angelfish
One of the larger reef fish around Pattaya, the Six-Banded Angelfish has a yellow body with six bold black vertical stripes. A true icon of the underwater world in Thailand, this fish feeds on sponges, algae, and even fish eggs—and adds size and drama to every reef dive.
Cleaner Wrasse
Small but fascinating, Cleaner Wrasse are the reef’s dedicated cleaning crew. You’ll find them hovering at “cleaning stations” where bigger fish line up for a scrub. These little guys might even give curious divers a once-over, just stay calm and enjoy the spa treatment!
Moon Wrasse
Bright, energetic, and constantly on the move, the Moon Wrasse is a flash of green and blue across the reef. It’s one of the more active fish you’ll see diving in Thailand, often darting around in territorial disputes. Watch for fast chases and vibrant reef drama.
Blue-Ringed Angelfish
The Blue-Ringed Angelfish is a shy but stunning find, with its electric blue rings and flowing yellow body. These larger fish cruise slowly along the reef, feeding on sponges and algae. Move gently and you may capture that perfect photo as it passes.
Cinnamon Clownfish (Red & Black Anemonefish)
One of the most loved and photographed tropical fish in Thailand, Cinnamon Clownfish live symbiotically with sea anemones. These bold little guardians patrol their host’s tentacles fiercely, making them easy to spot—and a joy to observe on any dive or snorkel trip.
Batfish
Elegant and social, Batfish are known for swimming close to divers with relaxed curiosity. Sometimes alone, often in small groups, they’re a popular subject for photographers. These gentle giants are among the friendliest fish in Pattaya’s waters.
