Pandinus cavimanus also called a Tanzanian Redclaw scorpion (along with a variety of other names) is a tropical scorpion with care similar to P imperator. The only cases of mistaken identity with this scorpion is with the P imperator but the differences are noticeable to the naked eye. Do not be fooled by their coloration. Some P imperators may have a reddish hue in the same way some P cavimanus have a blackish hue. The quickest way I've determined to tell the difference is the coloration of the telson. My P cavimanus's telson is uniform with the rest of it's body. Also the shape of the chela seems to be bulkier and more indented.
Enclosure: 5+ Gallons for a single individual with at least 10 for two or more.
Hide: Something they can bury beneath. I use a piece of wood from the pet store shaped like a cave with no bottom. I've found this species prefers to burrow down compared to my emperors which bury across. This could be a desire for more humidity which I have not tested.
Humidity: High ~75-80%. Keep the substrate moist but not sopping wet. The rule applies that if you wring the substrate it should not drip water. Keep a large water bowl for drinking and bathing purposes.
Temperature: Slightly lower than P imperator. Mine does fine at room temperature (A little over 72F).
Substrate: Some form of water retentive "dirt". I only have experience with cocofiber so I cannot say any alternatives. This must be at least 6 inches for an adult scorpion as they will very quickly become "pet holes".
Communal: Yes. I have heard sources claim they are extremely cannibalistic however I have never seen a problem in a well kept enclosure. I cannot say from personal experience as I only keep one but they appear to be as communal as P imperator. I will not recommend a cross-species enclosure with this species simply because their main defensive weapons (their claws) are far bulkier and further developed when compared to my P imperators.
Venom Potency: Very low. Not only is the venom of this species considered less potent than the P imperator, it is far less likely to strike. Only once have I seen a strike from mine and that was after a good 20 seconds of prodding (Uncooperative for a move). For the most part they lunge with their claws out-stretched at an disturbance. I receive a threat display any time I look into the enclosure. This is a more aggressive species.
Sexing: Sexing is similar to P imperator and Heterometrus sp. A quick glance at the pectines and genital opercula reveal the sex. Also from information received from another on the boards, the male has a tiny "tooth" on the movable finger.
PS: This is mainly from personal experience. Please feel free to correct/replace this caresheet as needed.
