About Misool Batu Kecil

Misool Batu Kecil, often referred to as Tank Rock, is a prime dive site nestled within the Misool area of Raja Ampat, part of the extensive marine protected areas. This site is an underwater ridge forming a natural connection between Boo and Kalig islands, showcasing the region's extraordinary biodiversity. Divers here encounter an explosion of marine life, thriving among some of the most colorful soft corals and expansive sea fans in Raja Ampat. The topography features a ridge that comes up shallower in parts, creating diverse habitats. The shallow sections are particularly rich with soft corals, while deeper areas host a variety of reef sharks and other pelagic species. The site is a macro photographer's dream, with numerous pygmy seahorses and nudibranchs hidden within the vibrant reef. Water temperatures consistently remain warm, typically between 27°C and 30°C, supporting an incredible array of species from tiny invertebrates to larger schooling fish.

Conditions & Currents

Currents at Misool Batu Kecil are a significant feature, ranging from moderate to strong, and are often unpredictable due to tidal influences. These nutrient-rich flows are responsible for the site's abundant soft corals and schooling fish, making a drift dive a common and exhilarating experience. Divers should be prepared for negative entries and maintain excellent buoyancy control to navigate the currents and protect the delicate reef. Reef hooks can be useful for observing specific areas without drifting away, especially when waiting for macro subjects. Visibility generally ranges from 15 to 30 meters, though plankton blooms, which sometimes coincide with manta sightings, can temporarily reduce clarity.

Dive profile & how the dive runs

Diving Misool Batu Kecil typically involves a negative entry to quickly descend onto the current-swept ridge. You'll often follow the contours of the reef, starting on one side of the ridge, allowing the current to carry you along the vibrant soft coral gardens. Depths can vary, with most of the action concentrated between 15 and 25 meters, where schooling fish and macro life are abundant. The dive often progresses towards the shallower sections of the ridge, where the soft corals are particularly lush. The turn point is usually dictated by air consumption and current strength, leading to a controlled ascent for a safety stop in a more sheltered area or by using a reef hook. Keep an eye out for larger pelagics in the blue and wobbegong sharks tucked away on the reef.

Underwater photography

Misool Batu Kecil is fantastic for both wide-angle and macro photography due to its diverse marine life and spectacular coral formations. For wide-angle, a fisheye or wide-angle lens will capture the expansive soft coral gardens and schools of fish; consider strobes to bring out the true colors. For macro, a 60mm or 100mm lens is ideal for pygmy seahorses, nudibranchs, and other small critters hiding among the corals. Strong currents demand excellent buoyancy control to avoid damaging the reef or stirring up sediment. Patience is key for capturing elusive macro subjects, and remember to respect marine life by not touching or disturbing them for a shot.
