Terumbu Tiga (or some dive books have it as "Tiger Rocks") is located to the east of Pulau Perhentian Besar. Boat journey from either Teluk Pauh or Teluk Dalam will take about 15 minutes.
In general, the visibility was quite good at about 10-15 metres with mild currents. Maximum dive depth is just about 25 metres but one rarely needs to go that deep especially if it is the 2nd or 3rd dive of the day.
Terumbu Tiga means "Three Reefs" in English, or rather a collection of 3 large boulder rocks that slightly juts out of the ocean surface. After the annoying fiasco at Tokong Laut earlier that left me with disappointment, Terumbu Tiga managed to make amend to my somewhat discontented day of diving.
During the dive briefing, the DMs mentioned about the chance to sight rare fish specie such as the emperor angelfish (Pomacanthus imperator) and bumphead parrotfish (Bolbometopon muricatum). I gladly spotted both of them! Other than that, I also saw various types of damselfish, a pair of nudibranch or sea slugs (Phyllidia sp., my attempt of macro photography left much to be desired though), blue-spotted boxfish (Ostracion cubicus), orange-spotted trevally (Carangoides bajad), etc.
Terumbu Tiga hosts quite an amazing collection of soft corals such as various specie of sea fans with a multitude of colourful feather of stars, harp gorgonian fans (Ctenocella pectinata), colourful dendronephthya soft corals, finger soft corals of Sinularia sp., a massive garden of whip corals, a great variety of mushroom and leathery corals, sea anemones, rectal coral (Symphyllia recta), table corals of Acropora sp., barrel sponges, etc. But the highlight probably went to this one expansive section filled with only mushroom leather corals of Sarcophyton mililatensis!
Overall, this was quite a great and leisure dive.
