Hello and welcome to FF! Insects should be sized same as distance between frog eyes. Otherwise frog can get impacted from undigested parts like the head. Crickets should be gut loaded for 24-48 hours with carrots, lettuce, oats and cherios. A better staple food are Canadian night crawlers. You can get the not dyed ones at bait shops. Will need to cut into 2 in. pieces from the pointy end. Once frog reaches 3 in. can feed whole ones.

Substrate should be mixed with dechlorinated tap water until damp and clumps in fist but does not drips water out.

Please remove heat pad from under substrate because it can overheat the frog. Relocate heat pad to an enclosure side and add a red bulb or ceramic heat emitter in a dimmer dome if needed to reach 82-84F during day with a few drops temperature at night. Good luck !
