Thanks for that Kelli! Glad to see the Afghanicus again! Especially "Mrs. Alien head"

Also, I traded the remainder of my collection (35 leopard geckos) to another breeder friend & she hasn't had a single problem...
What I believe happened is that somehow, that TPA het Ember must've gotten stressed, & the 1st thing that occurs in a stressed Leo is immune suppression, so that's my 2 cents on what happened with me & Pats deal. If the gecko in question had arrived in bad shape, of course I wouldve done something to fix the situation, but it didn't--it became sick over a few weeks. Like Kelli said--the strain of crypto found in leos is virtually symbiotic at this point...this strain of crypto is also species specific, meaning it only exists/thrives in leopard geckos. if you don't want to keep animals with crypto, then there are other geckos you can keep besides leos.
Thanks again Kelli for being a voice of reason!
