I don't really think many people allow their frogs to go into estivation unless they are trying to breed them. It's very difficult to care for them while they are in estivation, which is I think why most people don't do it. Some people feed their Pacman in a separate tank, others don't because it may be too stressful transferring them back and forth and they may not eat. I tried feeding my guy in a separate tank and he just got too scared and would not touch the insects.
