My BP's have no room to soak at all. The dish is an 8oz bowl and it is not full, so it probably has around 6 oz of water......about the size of a small butter. Basically, there is enough room for them to drink out of and thats it. I have considered just getting a large ceramic bowl to allow them to soak and keep the humidity up without spraying every 3 days. Where do you get your heavy bowls from?
