White's/Dumpy Tree Frog Having Issues

[Crispy42]

You can bowl feed crickets you just need a taller bowl. I would take out the sphagnum too since that's the biggest impaction risk.

What is the temperature and humidity in the tank? If she's been too cold that could explain why she's looking better under a heat lamp. Unfortunately heat mats aren't an ideal heat source for frogs so her environment could have been too cold. It also seems strange that she spends all her time in the water bowl, so I wonder if the humidity is too low?

Also, is the 10 gallon just a quarantine tank while she's young? An adult whites tree frog will need a bigger tank than that. Sanitation issues that result from a small tank can lead to health problems.

Have you seen her shed before? It's hard to tell from the picture but the white on her back could be shedding skin.
