My adult female Vaejovis Confusus lives happily in a BraPlast 3l tub which’s re readily available in Europe. Don’t know what the equivalent is over in the states but I’m sure google will give you the answer. Care is simple. 40-50% in the humidity on a substrate if either sand, coco fibre, peat or a mix of them works well. Temperature range of 25-30s. Lots of places to hide and dig as well. I will attach a picture of what I keep my scorps around their size in. They’re also aggressive eaters and very quick growing. This genus are one of my favourites.
