As for feeding, the betta should be fed just a pinch of food once per day, unless they are being conditioned, in that case 2-3 times a day is good. A betta should eat every day 6 days a week. It is good to skip feeding for a day just to let things move through. It is important to only give a pinch of food at a time. A betta's stomach is not very big, and too much food can cause Swim Bladder Disorder, in which the fish will become boyant and float on his/her side or back.
