Hey I have 2 emp scorps, an adult and one that is maybe half a year old. 2 days ago they must have dug a tunnel system in the tank and I haven't seen the Adult since then, is that normal? The little one peeks out every now and then but he gets scared when he sees me (NO i'm not that ugly =(). They haven't eaten in a week because they have refused food. I get the feeling that they probly tried to fight each other.
