Hey

,
Beardie's come from hot, dry and arid deserts in Australia. That wet mud can actually hurt your Beardie's health as they can't tolerate a humid enviroment.
There are better substrate choices for him. Some include newspaper, not the best looking but works very well especially for clean up. Other choices that would work are ceramic tile, reptile carpet (not indoor outdoor carpet) and rubber shelf liner. Also no sand as this can cause gut impaction, especially in small Beardie's. Just my 2 cents. GL
