So 6 days ago i added a male bipartitus to the tank.He went straight to the sand which i know it's what they do.I hadn't seen him since today.I was "tidying" the sand and i accidentaly touched him(he was in a completely different spot that he burrowed in the first day) and he went straight to the other corner of my tank and burrowed again.My question is did i just make a huge mistake and is he stressed so much that he might don't come out again?Also since i found him in the opposite corner from what he first burrowed,is it possible that he comes out at night when every light in the house is closed and what can i do to get him come out when my lights are on?
