Fukui, Bunaken: Coral Gardens and Reef Sharks

Fukui unfolds on the southwest tip of Bunaken, presenting itself as a large, gently sloping reef. As you descend, the reef's contour guides you, revealing an immense and lush garden primarily composed of cabbage corals. The topography here is not dramatic in terms of sheer walls, but rather a gradual incline that allows for a relaxed exploration of the vibrant hard coral formations, creating a mosaic of textures and colours that define this unique underwater landscape.

Almost immediately upon entering the water, you're likely to be greeted by a resident school of batfish, (Platax spp.). These inquisitive fish often cluster together, their broad silver bodies shimmering in the water column as they move with an easy grace. This consistent presence provides excellent opportunities for observation, allowing divers to appreciate their schooling behaviour and often surprisingly close approaches.

The deeper sections of Fukui host a significant sandy plateau, extending down to approximately 30 meters. This expansive seabed acts as a favoured resting ground for reef sharks, (Carcharhinus amblyrhynchos). You'll often find them quietly cruising or lying on the sand, a testament to the health of the ecosystem and a thrilling encounter for divers who approach with respect and caution.

Beyond the resident batfish and resting sharks, Fukui is also a known cleaning station for larger pelagic species. Tuna (Thunnus spp.) and barracudas (Sphyraena spp.) frequently visit the site, seeking out smaller cleaner fish to rid them of parasites. This dynamic interaction adds another layer of excitement, showcasing the intricate food web and ecological importance of this particular reef section.

As you ascend a little shallower, around the 20-meter mark, the reef's structure becomes home to enormous giant clams (Tridacna gigas). Their vibrant, undulating mantles create brilliant splashes of colour against the coral, and observing their sheer size and intricate patterns is a highlight. These iconic molluscs are not only beautiful but also play a critical role in the reef's filtration and overall health.

While the slope and plateau are central to the dive, the experience at Fukui is also shaped by the current. As you drift along, the water movement can vary significantly, sometimes picking up to a strong flow. This current, though challenging at times, also brings in the nutrients that fuel the lush coral growth and attract the large fish that frequent the site, ensuring a dynamic and ever-changing underwater spectacle.
