I use to feed daily but now I tend not to do that they dont need food every day . it can very and it doesnt have to be at the same intervals I find they eat better if its random. when I fed them the same time every day food would go uneaten if I did it sometime every other day and sometimes every two days they ate everthing. also varying food types is a good Idea I use about 4 or 5 different kinds of food
