Trigger Fish

By , 22 January, 2015, No Comment

The waters surrounding Koh Tao are home to countless species of fish, one of which is the Trigger Fish. Out of the 40+ species of Trigger Fish, the Titan Trigger Fish, the Yellow Margin Trigger Fish and the Pink Tailed Trigger Fish all claim these waters as home. During my Advanced Open Water Course, all the way through my DMT I was lucky enough to observe this fish through mating season when they live up to their infamous reputation of aggressively guarding their territory, through to their usual nonchalant chilled out selves.
During the last OW course I taught we observed a Titan Trigger fish feeding at one of our favorite dive sites, Twins. These fish use their fins to push sand away to get to worms and other prey. They also use their powerful teeth and jaws to eat the underside of a sea urchin that is softer and has no spines. These fish are infamous for their negative behavior yet show a higher intelligence than most other fish species as they have shown the ability to learn from previous mistakes.

Harliquin sweet lips

By , 8 December, 2014, No Comment

The harlequin sweet lips is a fish common to the dive sites of Koh Tao. It is a species of grunt native to the Indian Ocean and the western Pacific Ocean. It is a denizen of coral reefs found at depths of from 1 to 30 m (3.3 to 98.4 ft). It can reach 72 cm (28 in) in TL. The heaviest known individual weighed 7 kg (15 lb). This species is of minor importance to local commercial fisheries and but can be found in the aquarium trade.


Juveniles are brown with large white blotches and mimic the movement of a poisonous flatworm for defence against predators. As they grow older their brown spots change to black then yellow and black when they are fully grown.


These fishes have also been called Grunter Breams, Grunts, Rubberlips and Velvetchins. Fish ID is an adventure dive you can go at Davy Jones Locker which can be included in your Padi Advanced Open Water course.

Beautiful Parrot fish

By , 4 December, 2014, No Comment

When diving around the beautiful coral reef surrounding Koh Tao you will frequently come across parrot fish which you may hear before you see.

Not only are these fish beautiful with every colour of the rainbow but they are also very important to the survival of our reef. The grinding noise you will frequently hear while diving is most likely originating from the gnawing from parrot fish feeding off algae covering the coral. They are especially adapted to this task with their numerous teeth tightly packed which continuously grow as they are worn down. The result of which gives them a beak-like appearance, the reason for their name – Parrot fish.

By feeding on algae growing on the coral they are integral in managing the spread of algae, preventing it from choking the coral. Other rocky substrates they feed on are also ground down, digested and excreted as sand. This has helped to create beaches of many tropical islands as one parrot fish can produce up to 90kg of sand every year!

So next time you’re lying on a tropical beach in paradise just take a moment to think about the journey that sand has been on!
