Years ago I bought water moccasin's and western diamondback rattlesnakes by the pound for venom extraction.When they came in they were put in large cans with a solution of wescodyne and water to de-worm them, (you would not believe what can come out of a snake).It worked fast and never lost a snake using this process to de-worm.Anyway what got me thinking about this is the 3 legged RES that I have,the low weight could be caused by internal parasites,and not just unable to catch food.Has anyone ever heard of this method before being used on a water turtle or any reptile before.I know it's old school but sometimes old is better. Len--------Oh the WM were 50 cents a pound and Westerns were $1.25 a pound
