In captivity
Despite the risks of keeping such a dangerously venomous species in captivity, ''Androctonus'' scorpions are frequently found in the exotic animal trade, ''A. amoreuxi'' and ''A. australis'' being the most commonly available. The fat-tailed scorpion's main diet when in captivity consists of cockroaches, grasshoppers, and crickets. Scorpions will generally try to kill and eat anything which moves and is smaller than themselves. To simulate the desert environment, the enclosure used to keep the scorpion in must be kept at a temperature of between .
