| | Re: Sterilizing Blackworms?
I wonder if newts in nature have a choice... Of course some blackworms (or the in Europe available Tubifex) is normally found in polluted soils, but I doubt if you can erase for instance toxic things like heavy metals by just giveing them milk baths. Of course flushing them and feeding them something natural so that their intestinse are not filled with dirty mud anymore reduces pollution, but never all.
And I don't think their is need to, unless you feed your animals continously with the same type of food.
I use Tubifex for over 20 years in raising larvae of several newt and salamander species and never had sudden deaths or so, only when I did not wash away the dead worms in between them. And of course I also feed other things like Daphnia and Mosquito larvae (the red ones) but hey..both of these also occur often are caught in polluted water!
