New PacMan Owner needs tips on maintaining humidity

OK, almost all is covered by DH & Lija; just want to go back over couple things. Filtered water still has chloramines; which are toxic to frog. You need to transfer the frog to a small container (just coax it into the one used to bring frog from store) and remove all the substrate in tank. Now using new substrate; mix it with dechlorinated tap water until it's slightly damp and clumps in fist without dripping water out. That is the consistency you want to maintain with daily misting. Now you can bring container into tank, open top, tilt sideways on substrate and let frog hop out. I'm sorry since this will stress frog more; but it needs to be done. Please do avoid handling frog unless absolutely necessary and if so; wash hands well and rinse with dechlorinated tap before doing so. BTW, peeing on your hands was a defense mechanism, because it was afraid.

If desired do not need to throw out removed coco substrate, since it's only couple days old. Just place in a plastic bag and leave it open so it dries out next few days. When it does you can remove all pieces of moss and store it until next month when you will change the substrate. Then you mix it with dechlorinated tap as per above instructions and it will be OK to use. Spot clean after frog and pay attention when it moves from a spot to another one. It might have left you a present buried under the substrate.

IRT foods, crickets or dubia roaches need to be sized same or smaller as distance between frogs eyes to prevent impaction. Feed as many as frog will eat in 15 minutes and then remove uneaten ones so they do not pester frog. Night crawlers (not dyed) should be available at local Walmart's sport section or a bait shop. For a two in. frog would cut them same length from the pointy end. Your frog should be able to eat a whole 4-6 in. NC or 3-6 crickets daily. Once it reaches 3.5 to 4 in. and it shows a reduced response to feeding; you can go one day on and one off. Good luck !

So, I cleaned out the tank mostly because there was way too much water in the dirt. So I did clean it now.
I bought a new digital thermometer and hygrometer. The temperature is 73, and the humidity is 80%.
I'm going to put a heater near his tank, so that it gets a bit warmer.

And thanks for letting me know about the crickets. PetSmart said 2-3 every other day. =.=
I just fed him more now.

About the tank being too big, I thought the best was a 10 gallon tank. That is what I have been reading. For now, we have a 5 gallon. So now I'm a bit confused, I thought my tank was too small in the long term.
