oh and i forgot to ask how big are your crickets? I read a good rule is no food longer than the width between the froggies eyes.... but if they are stressed due to there lizard roommates... new terrarium... or any changes recently... they may not feel up to eating =(
You also dont need to get a friend for him they are pretty solitary lil guys that like there space. You could put one in a 55 gal and he'd probably be in heaven by himself till he's looking for a lady lmao!
