New to Pacman/frogs

[SapphireSky]

So after some research I bought a "regular" Pacman frog from my local Petsmart. He was $15. He was in a little enclosure inside the enclosure and was just burrowed with a few crickets in with him. I bought an enclosure and some new coco fiber and took him and the new enclosure home and got to work.

At first I had the coco SATURATED. I had never really worked with it before and actually ended up squeezing a lot of the excess water out which helped a lot. I don't have a heating pad just a UVA light on 12 hours during the day and then a a night heat bulb at night because the house does stay around 72°.

He had about 6-7 small crickets in his OG enclosure and I just put them in with him in his new home. First is that ok to leave crickets in with him (they were TINY)? Second, I tried feeding him a calcium dusted mealworm twice today and he didn't even flinch. Should I be concerned? Thirdly I bought TetraFauna AquaSafe water additive to make the water in my spray bottle safe for him it says 10mLs treats 10 gallons so I only put like 3 drops in 700mLs of water because I do have tap water which I used to fluff the coco fiber. And I've misted him a few times today. Too much? My digital hygrometer/thermometer won't be here until Wednesday but temp was around 83°.

Please help lol I just want to give this guy the best life possible. Thanks everybody.
