I tried again feeding them last night, but this time I payed very careful attention to the lights. I let the light from outside come through the window all day, and when evening came, I never turned on the lights and let the room naturally get dark. After dark I was very careful not to turn the lights on. I left a floating box of crickets with four crickets in it. At about 9:00 I came back to check on the frogs and found one of the frogs in the box and all four crickets were gone! i quickly added four more, and watched as the frog ate 3 more. Then he hopped out. I added seven crickets again to the box, hoping that the other frog would find and eat them later during the night. The next morning none were eaten. The frog that didn't eat hardly even moved at all during the night unlike the other frog. And today he hasn't been in a spot he is usually in.
Could the frog still be stressed? Is there anything more I could do to help?

i've also been staying out of the tank for the past few days (except to put food in and stuff) But I'll be especially careful to not stress the frogs anymore.
