Oh, I am so sorry!!!!
I've been through this lately with hermit crabs and tadpoles. Most people don't understand how we can get so attached to such little animals, but goodness knows we do.
It's the curse of the animal lover. But our lives are so much better for having known them, no matter how small.
Have you ever read about Rainbow Bridge? You babies are waiting for you there.
My deepest sympathy.
