I'm not sure it didn't work for me, people say they can be tamed, but when I need to take him out to clean cage the only way I can do is with gloves, he bites..... a lot.... and play dead...... usually I don't see him, only when the guy hungry and then he eats like n video and then burrows and I don't see until the next meal
Dan I'm not that brave to measure lol about 12-15" probably
