"Aubie", named after my workplace(Aubuchon Hardware) is doing well. I moved him from the top of my 75 gal to my floor. The only light near his tank is my defective alarm clock. I feed him trout worms and crickets. Seems to be eating them as he's quite fat. I see him come out at night when I shut down my other cages. BTW, mole salamanders do dig quite a bit.
