Gromphadorhina portentosa nymph enclosure acceptable?

[Grayman1984]

I’ve been wanting a couple of these for some time now and while I was getting some other supplies at petco I saw they had these in pairs as feeders and I snatched them up. I later bought a Rubbermaid brilliance 7.8 cup container to use as an enclosure and melted holes in the sides for cross ventilation and then added coco fiber, a piece of cork bark, a slice of squash, and a small water dish. Will this work for the time being or does it look too stuffy?

Update: I’ve since added a small vent to the lid of the enclosure.
