Aestivation temperatures

[BEETLE]

I have decided to have a go at breeding my bullfrogs, after a period of conditioning with plenty of food I was going to cool them off over the next two weeks, slowly letting their tanks dry out a bit and hope they would go into aestivation. (Hope because the large male never burrows or digs).
Reading around it seems that low temperatures during aestivation are needed if the females are to develop eggs and at the moment it is unlikely the temp will drop below 20 C.
I was wondering if anyone has done this, and what temperatures they used?

The temps should be in the mid to low 50s Fahrenheit (about 10-12 Celsius). What you're describing is too warm in my experience.
