@ MedicalAuthor- thanks for the update. I'm glad that you figured out what went wrong, & I agree with OatBoii that it's always best to plan ahead for the medical needs of our pets, just as it is for our own emergencies, & hold off before acquiring any other pets if finances are this tight. Pets are almost always more than just the purchase price, a cage & some food- even a tiny gecko can be a big responsibility when something goes wrong.
By the way, when I used to keep lizards (various geckos, a bearded dragon etc), I used to grow my own feeder mealworms- just the regular (smaller) size ones, & I'd feed them one at a time- offered from tongs- & with my tongs I'd pinch (destroy) the worm's head just as the lizard took it- otherwise, even the small mealworms have been known to chew their way out of a lizard that swallows them whole, without chewing. Keep that in mind for future reference. Their exoskeleton is hard to digest, plus the little stinkers can chew better than you think. All the best.
