I work at a nature center and we fed several types of feeder fish for our animals. We got a batch just over a week ago and now I see anchor worms on them. We have feed them to our Garter snake and to our Red Ear Slider turtle. Any ideas on if they can cause a health issue if eaten by a reptile? If I freeze future fish and feed them frozen will it kill any eggs or larvae?

Last year we had a terrible drought in out area. We had a Garter come up to our building starving. She found a toad and ate it, she was very thin. This proceeded to make her pretty sick. She wouldn't move just keep striking at anyone who came to close. We had classes going on and she couldn't stay there so I caught her up. Later I checked her out to see if she was hurt. I couldn't find anything so I was going to release her in the morning. Next day I realised why when she threw up the toad. She was not feeling well after that meal! We kept her for 2 weeks before she ate and then she went to town! By then she was so calm we decided to keep her. She is so funny. You could leave her cover off all day and she will not leave the tank! Lack of food and fresh water has made her rethink wanting to head back out of the cage. She went another month and had 20 newborns. I would like to treat her for possible parasites and later her young. Any Idea what I should use and dosage? Panacur or Praziquantel a option?
