Hello!
My beardie has a soaker dish he likes to lay in and drink from. It's made from a plaster/cement type of material. The problem with it is the large bump in the middle of the bowl keeps him from laying down in it. Rather than buying a new bowl I would like to sand down that piece. I imagine it is for insects to keep from drowning but he eats dubias and they tend not to get out of the feeder dish.
