She may go dormant somewhere (probably the least convenient spot in the tank) for a week. She'll hatch them inside her shell, likely, and release the little swimmers some night. I was fortunate enough to see it happen. Unfortunately they tend to get lost in the pumps or eaten by others. If you could set her up a smallish tank with identical water and have microshells available for the young when they settle to the bottom, you might stand a chance of some living. A bubbler might suffice. Note: immediately after hatch, she'll molt, which is another 3 days of sitting still. She hasn't died, just sits without moving. Eventually she'll resume activities, but may be delicate for a molt or more.b
