Thanks for the response!
The tail drop was so gross! It kept flopping around like a fish out of water long after it fell off. Creepy...
She is on paper towels right now. The only substrate is the moss in her moist hide, which she did go into when I placed her back in the tank. She still has a tank mate, because of a lack of space. Is that okay, or will that just stress her out even more?
I guess I will just keep an eye on it. About how long will it take to grow back, or at least heal?
