Borneo Diving in Sipidan Island

Midreef

Lazily decend to your required depth down the vertical wall that forms Sipadan Midreef, then just drift along with the current, whichever way it takes you - north or south. Once you begin your dive, it won't belong before you come across this sites most discernable guests - dozens of large green turtles, by now very habituated to inquisitive divers.

Drifting along the wall you'll soon be kept busy inspecting the dominant soft corals, navy knotted sea fans and orange gorgonian fans that hang from the ledges. Pygmy gobies and whip gobies are in abundance here. Forster's hawkfish are often seen hanging out, resting motionless on the small sponges. 5-lined cardinalfish and harlequin sweetlips move furtively under the many ledges and overhangs. Sulu fangblennies, known only to northern Borneo and the Sulu Archipelago, form aggregations among the gorgonians.

As with nearly all the Sipidan dive sites, Midreef can have quite strong currents, with an added tendency to push you upwards too. This occurs most often in the presence of cold water thermoclines rising from the depths. The trade-off though is that the adverse conditions bring with them higher densities of fish life. Large schools of moorish idols, redtooth triggerfish, unicornfish and bannerfish race along the wall. Smaller schools of round batfish pass by and Napoleon wrasse are regular visitors to this part of Borneo too.

The 6 metre hard coral flats that top the reef make an ideal safety stop. Small hardy stubbly table corals, and porites corals dominate here, and these form the staple diet for packs of bumphead parrotfish, sometimes 40 or so strong. Moving like a herd of African buffalo, munching their way through the dense bush, these largest of all parrotfish are a terrific sight and safety stops often become very long here!
