Frog is not eating! Please, need advice or help.

[Ra]

I have had my Female pacman frog for about 4 months now. (Since she was a size of a quarter) Lately she has not been eating, or eating VERY little. I fed her feeder fish for the last 4 months and she has had no problem digesting them or eating them. I fed her a feeder fish once a day or every two days depending on the size. Now I put the fish infront of her and she has no desire of eating. She just turns around. It's been a little over two weeks since the last time she was fed. (The fish are about half her size, sometimes a tad bigger) Then just recently I tried Crickets. I use to feed her crickets and fish for the first month I got her, and she ate about 7 crickets within an hour. I put 10 crickets, and I notice just 2 are gone within two days. And TRUST me, she's actually active for being a Pacman frog. She can seriously chase down anything she wants I always find a nice size poop even when she's not eating. So please help, her size hasn't decreased and her color is still the same so I am not too worried, but just in case something is serious, I want to know.

INFO:
She's an Inch 1/2 length and an Inch and 1/2 Width. She's not too big.
She's in a 10 gallon tank with 3 inches high of EcoEarth.
Temperature and Humidity are ALWAYS on the dot. (I always check twice a day and night. I also got the most accurate ones so I know for a fact it's not the Temp, or humidity. From 77-83 F and humidity is always around 76% to 80%)
I spray everything a few times a day with Distilled water.
I barely handle her. (I know how that stresses them out)
(Someone told me she's hibernating BUT she's always hopping around at night and sometimes during the day.)
I usually feed her at night, but also tried the day and still no eating.
There's a water dish. Also Distilled water.
There is Moss but only a huge chunk in the corner so she doesn't eat on it.
There are no plants, just a dish and moss.
and I usually clean the tank once every 2 months

I would continue offering the crickets as frequently as possible, make sure they are supplemented at every feeding for a frog this small that is still growing. I would cut back on the feeder fish, and consider the pacman food.
The ten gallon is fine, and so is the eco earth
What do you use to heat the enclosure? A warm area between 78 to 84 is perfect, and the coolest part of the enclosure can safely be between 72 to 75 degrees.
Spraing with distilled water is fine, but you want to use eitehr spring or tap water in the dish. R/O and distilled water can leach from the frog, as mentioned, when the frog is immersed in a body of this water.
The humidity requirements of Chacoan Horned frogs are a bit more broad ranged than most people realize. While high humidity levels are fine, so are considerably lower levels of air humidity. Relative humidity can safely drop down to the 60's or 50's at throughout the day, Misting the cage one to two times a day, preferably morning and night, and keeping the substrate moist but not soggy will keep the humidity at acceptable levels, even with a screen top. I've seen alot of advice to place plastic over a majority of the cage top, but for Chacoan Horned Frogs this is not needed. Fantasy and Surinam Horned frogs need a higher relative air humidity, in the 70's or up. Overly restricting air flow can cause problems in itself.
Good job not handling her often. Its not so much that they become stressed, its bad for their thin skin.
She isnt hibernating, but she may be taking a break from food. It happens.
Try feeding her at dusk, and warm the spray bottle by immersing it in a sink full of hot water and gently mist the frog. These warm water showers at dusk can sometimes induce a frog to awake, become alert and eat.
Use water treated with Reptisafe or a product used to treat tap water for chlorine and chlorimines used in fish tanks for the water dish instead of distilled water. Distilled water, as stated is fine for misting and it keeps the glass from getting spotted.
You could place a plastic vining plant in the cage, just make sure its to big for the frog to get in its mouth. You could also add functional decor in the form of a curved piece of cork bark as a hide.
What kind of moss? Generally, clumps of "sheet moss" have a lower risk of impaction that loose, long fiber moss.
I would replace the eco earth and clean the tank at least once monthly, changing the water dish every day or other day and obviously when it gets pooped in.

The frog isnt losing weight, and it isnt dehydrated, so it sounds like you are doing fine and so is your frog. At this point I see no reason for you to take any action aside from perhaps offering a warmer hot area in the enclosure.

Giving your frog a diluted pedialyte soak a few times a day isnt really necessary if the frog is hydrated and not losing weight, but it may need an appetite boost so it wouldnt hurt. But also, try what I suggested about feeding at dusk and spraying with warm water before offering food.
