Bettas also have the biggest occurence of constipation of any fish I have any knowledge of and to feed them consistently is a good way to keep the digestive system moving at a steady rate. It is important to control them so they are not stuffing themselves and making sure that they are getting some greens every week and for some reason peas do work the best. I do not know why they are so prone to this but I have never known of a poorly fed or overfed betta that has not suffered constipation at least one time and perhaps more. One thing is for sure, if they ever are constipated it makes it doubly easy for it to happen again so prevention is definitely worth the effort.
Poe is correct in saying that most fish can easily go without food for a period of time with no damage at all, in fact I have read articles on the fact that obesity is becoming a problem in a lot of aquariums. However, it is also correct that to the Betta, mealtime is a socialization experience as well as a nourishment. It is for that reason that I suggest never missing a feeding as the Bettas never really bond with other fish, but they do with you. They consider themselves more like you than like the other fish around. If you withhold food they probably would not miss it much but when you do not show up to play they do miss that!! (even if they act totally bored
