Those cages look pretty cool but will be more effort to maintain. I have a wood and glass display for my gtp and it takes more effort than her old plastic cube, but it makes for a nicer display which is what I wanted. If you're wanting a nice display I would do the lids differently and use RHPs...I've used them with bloods, and with my current ball, without any issues. If you want a lower maintenance set up, go for plastic enclosures.
