You nee to do as Lynn has stated above. Keepthe climate very consistant with minimal fluxuation. Feeding your crickets with fruits and veggies does help, but most of the time is not enough. This is why you should supply supplemnts by dusting their. Food. It adds extra benifits.

Your frog is in very bad shape. I suspect parasites may be attacking your frog due to how emaciated he is. A vet trip is needed ASAP and I would provide a fecal sample to take with you for testing.

Still perform the Pedialyte soaks. Make sure they are warm not hot. Luke warm is safest. Around 72 to 77 degree water. He needs to be in the bath for minimum of 10 minutes per soak and you can perform this daily for up to 2 weeks.

I am no expert and do not own Red Eyes, but I can honestly say that your frog is in a lot of trouble right now. If you have to you can support your frog in the bath. Just be careful not to harm him or allow him to harm himself.
