It has been three days, and Lefty and Digitalis have at least 100 small fry that have been swimming and eating baby brine shrimp for two days. There are no remaining fry from the previous spawning, but these fry seem healthy.
Hopefully, the situation with nonviable spawnings has passed.
Update March 10. 2010
A week has passed and there are still at least 75 fry surviving.
