I'm living in the south of France and have captured what I am almost certain is an E. Flavicaudis. There's no known problem with thinning scorpion populations down here as far as I know, and I'll be moving within the year so it'll be released then at worst. I just want to keep it around to observe it.
I have it in a converted Candarel jar (this is a circular jar, 8cm in diameter and about 20cm tall) with nine small air-holes in the lid. I put about a half inch of (fairly dry) dirt on the floor, along with a twig and a piece of terra-cotta angled such that it can use it to hide from any light in the room. I'm not using any special heating equipment, I keep the windows open in here and don't have air-conditioning, so I figure the normal room-temperature should be what it needs. I cleaned out a bottle of nasal spray and filled it with water, I give its jar a couple of spritzes a day to keep the humidity up.
I have yet to feed it, but I'm planning on just catching small flies and other insects and giving it one or two a week, is this a good idea?
Am I doing anything wrong? Does it need more substrate, more moisture? More space? Should I get a hygrometer?
