Hey guys does anyone have experience with these guys? I got one a few days ago and he seems happy and healthy. I don’t have any sand sifters so I thought he’d help. He’s currently digging tunnels moving a ton of sand and has made the tank dirty. Granted it’s been set up for around 6 years with no sand shifters. So I thought he may just be having a field day and will settle down once the bed is fairly clean. Any advice will help.
