Thank you people of the world �� I have him in a 20 gallon tank and I know that's way enough space for just one frog. I'm going to try the bowl feeding method and cover 3 sides of the tank, and I actually just have the crickets roaming around the tank�� ha yeah I should take them out lol, And him getting used to the tank makes more sense for his behavior.

thanks again for these wonderful answers, I appreciate ur time
