Is this normal frog behavior?

I got a smaller enclosure, but the pet store was almost out of crickets due to a snow storm. I tried putting them in the tank but they all promptly drowned themselves as far as I can tell. Also, every time I mist the tank the temperatures go way down, out of acceptable range. Any way to prevent this?

Also, I can't tell if it's because of the smaller tank or ehat, but he seems to be glistening a bit. Here's a picture that I took while soaking him in hot water.
