Glad to hear you have experience in breeding torts. Maybe you want to use a nicer tone when responding to the experts you asked for help next time? Because that is what you did. Asked for expert opinions in why the imports are heavy with parasites. Only you sound ungrateful and rude when people reply. As the other responder could not have known what, if ANY, experience you have but you attack them anyway for imparting a little education. Poor form.
Another thing - you mentioned to the effect that you were not interested in the 4 inch CB's because you wanted to breed. News flash. Breeders do not have any problem raising healthy torts for later breeding projects. But then they are in it for the long term, of course. Since you are obviously not interested in anything people have to say I'll cease to read your posts. Go dig up whatever information you want to hard way - research it yourself. Do what others do and dig thru published reports and papers like others do. Good luck with whatever you have or get.
