This was my thought exactly. Though I am no where near educated in this hobby as others are. I was sure that there must have been biological benifits. My sand bed is 3" so it's not DSB but I have lots of wrasses and gobies that sleep in sand
Ive seen my fish bolt into the sand and would be worried that they may hurt themselves if it wasn't deep enough
