Dumpy frog not eating well

[nono]

Hi. I want to ask a question. I have a dumpy frog for more than a month. At first 2 weeks he always eat 6 or more crickets a day which i dust it with calcium triple times a week. Now he is kinda lazy chasing down the food although he is still eating every 2 or 3 days about 3 or 4 crickets. The temperature is around 28 to 30 degree celcius and humidty around 60 percent to 75 percent. The colouration is almost always dark brownish green except when i take him out to give him a bit of sunlight at the morning for 5 minutes. Thats when he start to turn pale green again. I will upload the enclosure photo. The poop is same as usual which is kinda cylindrical and dark brown. Do you guys got any idea what is going on? Thanks a lot

Well that's unusual because this species is known for being a voracious eater. The temperature seems fine. Do you lower it at night? Perhaps add a few more hiding places. I'm a big fan of live plants in my setups. The tank seems a bit bright, partially due to the paper towels I think.

Hmm lower but not much. Maybe you are right about the brightness. Okay thanks i will give it a try
