Littlest pup is about 2.5 inches and she is just over 3 months old . Other 2 are 6 months and 10 months and about 4 inches and 5 inches. These are 3 females that I kept from previous litters although I think I have sold them now to Miles. Expecting litter number 7 any day now and not sure if it will be 100% retic or retic x hystrix we shall see. Pups are in a 100 gallon tank that is plumbed inline with the 750 that is in the basement. So they are on the same water as the parents and more water volume but they are easier to feed and I get to enjoy them in my bedroom
