    Emergency Care for Desiccated Frogs
    If a frog escapes and is found dried up, do not assume it is dead. They have amazing powers of revival. Place the frog in a shallow bowl of tank water with its nostrils above the water to allow it to breathe. Let the frog rest in the water and watch carefully for movement of the nostrils. It can take several hours for the frog the rehydrate. Once the frogs is able to swim a bit, keep it in a bucket with a few inches of water (or lower the water level of the tank) so it can reach the surface easily for air while it regains strength. Be patient, and do not attempt to feed the frog until it is fully recovered.

    Good luck, I hope he recovers.
