As slings they DO tend to burrow. The adults IVE had, i kept nice and dry. (basically housed them just like my rosies.. Maybe misted lightly once a week) for slings, id reccomend standard light mistings every few days. Scavange the house for somethin. I saw jaimies add (im a member) and at 2i I would imagine them small. Like babyfood jar small. As time progresses move them up accordingly.
All in all, they are AWESOME ts. i would reccommend them to ANYBODY in the hobby. Once they hit a decent size they get bolder and make an AWESOME display t. Always out in the open, cool as hell to feed, and they get huge.
