10 gallons more often than not does not cut it for such a small animal, trying to replicate the breeder's setup until the animals eat and put some weight on is key.
Switch the BP to a 6 quarts tub max until it reaches 150/200 grams. (Security is the number one priority for hatchling that small)
Use aspen as bedding. (Provides additional security)
Provide a hot spot of no higher than 86/87 (in a tub that small to high of temps do not allow much room to get away from the heat if the animals feel the need to)
Offer a 6 inches plastic flower pot saucer as an hide. (Provide tight hiding place = increase security)
Once you made the switch wait a week and offer food in the tub, offering a LIVE mouse hopper. (Getting the animal to eat is priority number one, once consistent you can attempt to switch if this is what you want)
DO NOT handle your BP until it eats for you 3 to 5 times and keep it to a minimum until the animal is a bit bigger.
