Hello, new Pacman frog owner here

[xghostmakerx]

Hello, my son who is 8 and I recently purchased a Pacman frog so I wanted to sign up here, post a few pictures and maybe get some advice on how to keep our little friend happy and healthy. We purchased "it" (as Petsmart was not sure of the gender) last night and got some of the essential supplies but wanted to see what else I could get that he (lets pretend she's a boy) needs. The enclosure we purchased is a 10 gallon tank and it came with a top an analog thermometer/humidity gauge and a light. Its pretty nice I think but its super large for him. We also purchased 30 crickets which we keep in a critter carrier. We feed the crickets some potato as instructed by the employee at the mart of pets. We also got him a log to hide in and a water bowl. We intend on misting him at least twice a day with bottled water as well as change his water daily with bottled water as well. I put about 6-8 crickets in the enclosure with him since the cage is large and he just kind of hangs out and burrows in the mulchy stuff in his cage. We got these three bricks that we had to take one and soak it in water until it came apart and we use that for his bedding. I keep a thin layer of it on the bottom of his cage.

So far he seems happy and healthy although I haven't seen him eat. I think there is one less cricket than we had before but its hard to tell. They are tiny and move around a lot. My son does want to take him out of his enclosure and have him scurry around on the floor of his bedroom which is actually pretty cool. He certainly moves more on the floor than he moves in his habitat. I do make sure my son washes his hands before and after handling him. My son has a lot of experience handling backyard toads and frogs so he knows how to carry it so that it doesn't jump out of his hands. We haven't picked out a name yet but I think we're leaning toward "Jabba".

Temperature in the tank is currently around 75% but the humidity is only around 50%.

I wanted to check on preferred food for them. Crickets are fine for me but a hassle. I'd much prefer something I could keep in the fridge like worms but I worry a little bit about him getting enough to eat with the large enclosure. Does he need to come out and go into a smaller enclosure to get his fill?

Ok, so advice would be nice at this point. Any pointers?
