Would a 10 gallon be to small for 4 emperor scorpions?
Excellent advice!Possibly . . . are they adults? Most people seem to reccomend something like five gallons per scorp when adult, but some have had success with smaller spaces. In most people's experience they all tend to pile under the same hide anyway.
I'd give it a shot, but if territorial disputes don't settle down soon, try separating them.
