Hii, what should I buy for a rhino beetle?

Hii everyone
I`ve kept a lot of exotic pets before, like madagascan hissing cockroaches, emperor scorpions, praying mantids, african land snails, lizards and snakes etc. I want to buy a pair of some type of rhino beetle, but I do not want to get ripped off at the pet store as I always seem to buy things that I do not need. Can anyone suggest what I should buy for a pair of rhino beetles and tell me the tank dimensions and care etc..
