The dragon fish is known as bottom-dwellers since they inhabit in deep sea water where there is no concept of sunlight. These types of fish are found in the Indian, Pacific, and Atlantic Ocean in Vietnam, Cambodia, Indonesia, Malaysia, Myanmar (Burma), Philippines, and Thailand. These species are found at a depth of about 1,500 meters. 2  The dragon fish is known to migrate vertically whilst capturing its prey. 3  These fish are capable to swallow almost anything that fits into their mouths; however, they are often found to eat larger prey including shrimp.
