Hi, I plan on getting a beetle as a pet. a dynastes tityus or a lucanus elaphus depending on what's available. what all would I need to properly take care of them? I have a terrarium that's about 18x18x24 and a heat lamp. I watched a video that said I'd need a substrate and that getting a insect friendly compost and mixing it with decaying wood and leaf litter would be alright. coincidentally my friend just had a tree call in their yard and was gonna check it out to see if I could use it. I was also gonna buy a mist bottle at the store and beetle jelly online. is there anything I'm missing or I'm misinformed about? Thanks in advance!
