Also from reading in your other post you just moved him again to the enclosure where you used to keep your crickets, so that again is a new environment to him/her, try and offer food after a few days versus right away, these frogs or many animals for that matter stress out whenever their habitats change. Be patient after moving him from one an enclosure to another. I don't even attempt to feed until after about 3-4 days after the frog has settled in, i have yet to have a frog not eat using this method. When wiggling the worm use tongs if you have, i use med size tweezers you can get at petco.
