I'm very sorry to hear that, Don! Sounds like there was definitely something wrong with them from the store. It could be an isolated case of the store getting a bad batch of iggies from their supplier, but you should consider that every reptile in their store could be infected now. As could your own reptiles. I'll second what Becky said...get the rest of your guys to the vet ASAP. If you haven't disposed of them, maybe you could get a necropsy done on one of the lizards to find out what killed it and if the rest of your collection is at risk.
