Don't want to make this too long, but there are actually many signs. The most obvious are fleeing, digging, or assuming a defensive position. If the scorpion wanders too much in daylight hours through the enclosure, there could be something wrong. To the extreme, some scorpions may refuse food or become aggressive or even cannabalistic.how would you know if it is stressed anyways? Just curious
If it's in a new enclosure, it should be alright. It is just getting used to the new environment.I just put mine in a new terrarium yesterday and hes gone into hiding maybe for a few hours, the rest of the time hes spent climbing the walls and even hanging up side down on the ceiling for the better part of the day! I always thought that it was normal for them to explore even during the day time?
