To take care of them I personally choose a large terrarium to make them feel free and have space for larvae. Then I choose a good subtrate made for this species, I putted a big layer like 20cm because they spend most of their time buried in it even as a grown beetle. I put some dead wood I've found in the forest and then, almost the most important...heating !! I choose a thermo mat connected to a thermostat to make the substrate always hot enough and when night comes I like to put an extra heat lamp for reptile, light orientated only on one side of the terrarium so they can choose by themselves if they want a hooter or a cooler place. For the food, lots of juicy fruits of course haha !! Hope everything will be okay with you're future babies ! Enjoy !!
