This can be a very good dive from a boat or the beach. As a beach dive you want to time it correctly; either about 45 minutes before high or very low tide. At these times entrance and exit will be easiest. Regardless of when you plan it, you need to be aware that very strong currents can occur at this site. These currents can pull you seaward, or under the coral ledges.
Park at the Asan park and make the short trek to the dive entrance. The cut begins approximately 30 feet out from the shore. Once you drop down into the cut, you can head either right or left. Going left is the preferred choice as it leads directly to open water.
Tall limestone shafts extend up dramatically and many are covered with marine life. These shafts that are characteristic of this dive offer swim-throughs and crevices, giving ample opportunity to see a selection of lionfish and turkeyfish, who like to hide in the overhangs.
Gobies are small fish which generally appear to be “sitting” on their front fins. They often are found in pairs and will make homes for themselves in sandy bottoms. Since these fish don't have a swim bladder, they are bottom dwellers. Most are usually no bigger than 4 inches long.
Many of the gobies live in close association with invertebrates such as sponges, shrimp, and sea urchins.
The gobie forms a symbiotic relationship with small shrimp. The shrimp constanly dig and lcean their shared burrow home, while the gobie keeps a sharp vigil against predators. The gobies eat micro-fauna they find near the bottom, the shrimp feed on what they find in their burrowing and around the opening.
The shrimp are virtually blind and use one of their antennae to constantly touch the gobie. When threatened, both retreat into their burrow.
