Gobies are more of a bonog or a bogo in cebuano, and when it comes to halwan, there are 3 possible kinds of fish that are associated with that name, depending on who you ask.. Sometimes a halwan can be a snakehead, a climbing perch or a catfish.... some would say halwang tasik (snakehead) or halwang puyo (climbing perch) sometimes diferent places may have different names.
