How long does it take for a new frog to be accepted by an older frog. Gru and Kimchi have been together for over a week now and you can tell they are not bonding. First off they always sleep on opposite sides of the tank. Never near each other. Plus, they are rarely awake at the same time. If Kimchi wakes up and Gru is up then he immediately goes back to sleep. If Kimchi is already awake and Gru wakes up he goes to the ground and hides behind the fountain. Gru is king of the fountain, he perches there and calls, we have yet to hear Kimchi call as far as I know. Where he stays until Gru goes back to sleep.

Is this normal? Will it fade? Or are they just destined to stay away from each other?
