Dude. . . chytrid is an example I used. Pancur is for some endoparasites, chytrid is a fungus. I thought I was writing to someone that could keep up with an educated conversation.
Hahaha. My points were subtle.
1) We don't know what healthy levels of "parasites" are for most species, and it's imprudent and unjustified to assume killing them all is appropriate.
2) If you want to kill off all parasites (i.e., why you advise pancur) you'll won't be able to kill them all - namely, fungal pathogens.
3) Good quarantine and sterilization measures are what really matters, but this wasn't a discussion about quarantine, was it? It devolved into a hissy fit about prophylactic treatment.
4) If you want to keep up an educated conversation, it's silly to suggest that animals as evolutionary divergent as anoles, eublepharid geckos, and varanids will readily exchange the majority of their pathogens/parasites. That doesn't consider the numerous life history and physiological adaptations pathogens/parasites have to their hosts.
I understand there are often many successful approaches to husbandry. My approach seems to be working for me; my life list for squamate species I've bred is over 150 (still humble by many standards). What's your tally?
