Androctonus is the genus that contains the commonly called Fat Tail Scorpions. As the name suggests, these scorpions have an enlarged tail that allows them to possess more of their already toxic venom. They are recognized as some of the world’s most dangerous scorpions, and this should be kept in mind when choosing housing and while performing cage maintenance. The two most commonly available species in the U.S. hobby are the Yellow Fat Tail, Androctonus australis, and the Black Fat Tail, Androctonus bicolor. The care for each one is nearly identical as they are both naturally found throughout Africa and the Middle East.
Scorpions naturally have a slow metabolism, as they spend much of their time in burrows and under rocks. Because of this, they don’t require too large of an enclosure. However, they love to burrow and rearrange their cage, so one that allows burrowing is preferred. A cage size similar to a 5-10 gallon tank will be plenty large enough. The 12x12x12 glass reptile tanks offered by Exo Terra and Zoo Med make perfect and secure environments for these scorpions, as a lock can be purchased for added security. Since they are a desert dwelling species, a substrate that is dry and does not retain humidity is a must. I personally use a half-and-half mix of Zoo Med ReptiSand and Excavator clay. This allows your scorpions to dig and burrow as they would in the wild. Sand can also be used by itself, though you will want to offer more places to hide, such as flat rocks and wood. As for temperature, 75-80 degrees Fahrenheit is ideal. This can be achieved by placing a low wattage heat lamp on top, or a heat pad stuck to the side. No special lighting is required as scorpions are nocturnal. They should be offered one or two appropriately sized crickets or roaches per week. A small water bowl can be offered, or the cage can be sprayed very lightly once or twice a month. They don’t require a lot of water because they get most of it from their food.
All in all, they are an easy-to-keep pet that doesn’t require daily care. If provided with a red nightlight, they can be seen throughout the night digging and rearranging their decor. However, they are a highly venomous animal that should be treated with respect. Their toxicity matched with their defensive personalities makes them a species that should only be kept by the more advanced and responsible hobbyist. Long tongs or hemostats should be purchased for performing maintenance, and under no circumstance should they be handled. If you’ve owned a lot of other scorpions and are ready to take it to the next level, then the Androctonus genus may be a good addition to your collection.
