Crickets are a pain. If you can get away from feeding him crickets, I suggest you do. Crickets are a mission and they are loud and stinky. If you could, feed him nightcrawlers that would be great. I feed my pacman dusted nightcrawlers and she loves them. Nightcrawlers are great for these guys, easy to maintain and even to breed if you wanted to. Plus they are quiet and don't stink. Plus they can live for extended periods of time with little maintenance, unlike crickets. I would say once nice size nightcrawler is equivalent to 5 large crickets at least. I also give my frog some fish from time to time, not often. Pinkies as a treat whenever I am around a pet shop that sells them alive not frozen. No more than once a month on the pinkies btw. My frog also likes that pacman food zoomed sells that you wet and roll up, smells like cat food lol. Take some of it and fit into a cricket mold and fed it to your frog, he wont tell the difference..LOL JK. No hoppers or mice, they can hurt your frog. Good luck
