Hello and welcome!!
i noticed a couple of things wrong here.
First and formost:
Do not house ur beardies together this causes stress and makes em go off their food. bds are solitary animals and only ever come together to mate, therefore they need their own vivs and own setups. They will do sooooo much better if you separate them. They will also fight i guarantee it. it might be in a week or might not happen till next year but it WILL happen and could at anytime. So they need to be separated as they could loose a foot or even a life! its waaay to risky.
Your basking is a little too hot it needs to be around 100-105.
Wax worms are fatty and addictive and should only be a treat. But crix are fine try getting some super worms they are good.
Also did you only JUST get them? if so they wont eat much due to relocation stress. It cant be helped and its normal, and can last up to 2 weeks and they should not be handled or disturbed during this period except for feeding and removing poo.
What are you using as substrate? if its sand of any kind, turf it out especially if it calci sand as much as you may have been told it good for lizards, its DEADLY cuz it turns to concrete in ur beardies tummy, so people here have aptly named it death sand. any loose substrate is bad cuz young beardies like urs lick things A LOT!!and could eat some by mistake causing blockages . Good things to use are reptile carpet, slate tiles or paper towel.
With young beardies the live feeders need to be dusted 5X a week. you should also be offering greens daily.
Heres a good site for reference we all recommend it.

The Reptisun light is an excellent light and it needs to be changed every 6 months cuz the uvb output gets less and less as the light gets older.
Sorry if i sounded like i was being nasty! i wasnt im just trying to stress the crucial points!!
i hope this helps with ur problem and you must post pix else you will be hounded for them!! (we love pics)
Oh yeah if you have a bowl of water in ur viv this could be raising the humidity too much and putting them off their food also . So depending on if you see ur beardies everyday take it out and
bath them in a tub or sink in warm water for about 10-15 mins. This is the best way to for them to get water just make sure their bum is in the water as this is where they absorb it from, you can do this everyday or every 2 days its up to you. The water should be no deeper that their arm pits.
Good luck with ur little guys!! i hope to see some pix up on here soon!!!
Sorry again if i sounded like a nasty old lady yelling at you!!!!!
