Sorry you are having trouble
I have never kept this species of frog.
I do understand however:
-their temp and humidity needs are a bit tricky to maintain:
Temps:
a day time temperature range between 75-82 degrees F.
-Some care sheets will say up to 84
Maintain night temperature range between 70-74 degrees F.
Humidity:
low to moderate levels of humidity – 60% max This is very important ! Therefore daily misting may not be necessary
remember they are from dryer 'natural' habitats
- so you want to have a few humidity gauges in the enclosure in different spots
Plus they need - a well ventilated enclosure
He needs UVB lighting
You will want to get rid of the substrate !!!!!!!!!!!!!!!!!!!!
He could possible swallow some causing an intestinal obstruction.
I would replace it with slightly dampened paper towel ( just damp enough to keep the paper towel flat)
"He is the only frog in the tank as we have a 30 gallon tank with fire bellied toads"
Sorry , I'm confused .............do you mean he is WITH the toads?
If so ( YIKES) you ABSOLUTELY have to move him- ASAP
Sorry if I don't understandwhat you meant by this
How long have you had him ?
Are you dusting the crickets with Calcium and vitamin powder ?
How often?
Are you using a feeder bowl ( or do you let them roam on the substrate ) ?
He is small ---- What size crickets are you feeding him ? ---they should be small
-if you are not using a feeder bowl then you really have no idea if he has eaten them
Are you de-chlorinating the water ?
The soaking in the dish thing:
could mean a few things
***** intestinal blockage ( have you found poop lately ) *****
-parasites ( detected by a fecal test / by a vet/ then treated)
-simply needed to soak
-is ill and was too weak to move and/or climb
Please read carefully, correct and/or do additional research on the proper husbandry of your little guy
Possible make an appt with a herp vet / experienced w/ this species
If you do not have one; you could email Dr Frye --- It can't hurt to have a conversation

You could answer the ??? above and we can move forward
BTW - detailing all of this information in an email to Dr Frye will be necessary as well as the frog's length snout to vent
( tip of his nose to the very end of his body between his legs)
Handle him only when absolutely necessary, when you have to do this use powerless non-latex gloves.
If handling is necessary and gloves are not immediately available... wash and rinse your hands...make sure your skin is dampened with distilled or his de-chlorinated water.
Keep us posted
