Abc House Reef

Tioman Island sits off the east coast of Pahang, Malaysia, in the South China Sea, ringed by fringing reefs accessed from its coastal villages and resorts. ABC is one of the small bays along the island's western side, where the house reef extends out from the shoreline in front of the beach chalets, reaching a maximum depth of around 25 metres over a reef bottom and rated a beginner dive. Nudibranchs are a regular find here, and divers have also reported barracuda, cuttlefish, grouper, frogfish, ghost pipefish, and even blue-ringed octopus and mimic octopus on the reef. Some plastic debris has also been noted at the site.
