I love those Elvis videos too! Too funny!

Kisa, your tank looks great by the way, love the background!
I'm thinking your little guy wants to get to his tank mate! They will be buddies soon. I find that they are very social frogs, and they have just gotten settled in the tank and exploring and experimenting with escape techniques...lol

There seems to be alot of "hides" for them so they feel safe and secure. Maybe darken one side of the enclosure with a cloth or cardboard on the outside. But otherwise I think it is very normal behavior, and they are "testing" the limits...lol

Also up his food intake (a little), one cricket every 3 days would make me cranky
It is also a good sign that they are adjusting well when they are eating and growing, so good job!

Keep us posted on how they are doing.
