This is a common marking known as full mask. If your betta's head isn't usually black but it has gone black, it's probably a bacterial or fungal infection. I can't make an accurate diagnosis without a photo and some history, but generally fungus will appear fuzzy (and more often white than black) while bacteria might look slimy or like the skin is fraying away. Make sure the water quality is acceptable (the tank is large enough, heated, and no ammonia or nitrites present). For more advice: www.fishforums.net
