lots of caresheets say you can feed them once a week and they will be fine...just be sure to feed it all it will eat in 15 mins....if it was my frog i would feed it twice a week....i feed my 6 month old male about every other day...and as for what to feed? i feed him dubia roaches...one male roach is like eating 3-5 large crickets so he just pounds on some of them till he stops eating...but u can try roaches or nightcrawlers...some pixies have problems eating nightcrawlers though...they try to lick them up and they are too slimmy that their tongue doesnt stick to the nightcrawler..hope that helps
