Succulents like as much bright indirect light as you can provide.
Allow the soil dry out before watering, then water deeply and thoroughly. Never allow a succulents to sit in water. Over-watering is the main reason succulent plants die.
This plant does well in very low humidity.
Use a fast-draining, porous, sandy soil to prevent over-watering and root-rot. You can purchase special cactus/ succulent soil at a nursery or make your own.
