i bought two young leopardgeckos (one 3/4 years old, the other a few months) from a local breeder about a week ago. they looked healthy to me. the first day i got them i offered them some zophobas, which i did cut in half. i didn't expect them to eat, since i've heard that they sometimes don't eat for days when they were transported, but to my surprise the bigger gecko was interested right from the beginning and ate. the little one didn't seem to care much for the food i offered, although i cut them in small pieces, so i left them in the terrarium. the following evening when i cchecked on them again, the little one had a swollen, dark belly. i panicked and googled and soon was pretty certain that he was impacted. the previous owner did let them live on some kind of red sand, most of his other geckos were on calci-sand. my terrarium has a stone-floor and no loose substrate. i planned on observing him closely for the next two days, so that if his situation would not improve i'd call a vet at monday. after reading about tipps on how to treat impaction, i gave him warm waterbaths and a few drops of oil to help him pass the food/sand. it seemed to work and he did poop, although it was mostly diarrhea and didn't look like the impaction was gone. i stayed awake all night, checking on him every now and then. the next day he did much better, atleast i thought so. his belly was almost not swollen anymore and less dark. i gave him another waterbath in the evening, when he suddenly started spasming violently for a few seconds and then stopped breathing. i totally panicked again and tried to give him cpr for about 20 minutes, but he died. i'm devastated and worried for my other leo. can anyone tell me why the little one might've died and whether the big one is impacted or not?
