Those guys can be pretty active at night and can jump great distances. I would suggest going with a 20 gallon. A screen top locking lid would be best and then you could cover partof it toget your humidity right. You'll find the more densly planted your tank the easier it is to keep consistent stats. If you follow the guidlines of properly setting up a tropical tank with the correct soil, drainage layer and lots of live plants care is rather simple. Also look at getting springtails and isopods to put in the soil and they will help with the decomposition cycle.
