If you put soil in the bottom they’ll lay their eggs in it. I use the gel crystals so they have plenty of moisture without drying out. Mine have bred in the bioactive bearded dragon viv which is great as I can use the babies for anole food. Been trying to breed them in a big tub as food and a couple of hideaways must have bred in his viv. They like it hot and if you give them plenty of ventilation and hiding places they should breed.
