My first night dive was as part of the Advanced Open Water (AOW) course, so I did it with an instructor. I encourage you to do it that way.
Of course, even diving with an instructor as part of a class does not guarantee things will turn out well. On my first night dive, not only was I in the water as part of my instructor's group of students, but there were also several other instructors and their own groups of students. With all the lights flashing around, it looked like a disco. I found it difficult to avoid getting confused about which group was which. I was so focused on just trying to stay with my group that I don't think I noticed any interesting marine life. I am not trying to scare you. Rather, I hope you learn from my story and, on your first night dive, try to avoid diving with too many other people in the water at the same time. Once you get comfortable with night diving, it is a lot of fun.
