Glass enclosures are not really practical for roaches. A 20 gallon has a lot of empty room for only 200 blatta lateralis. They like it very dark. Like absence of light kind of dark. Plastic bins also have rounded corners and come in solid colors. They are also easier to keep clean. nymphs and other non climbers can also sometimes climb up the silicon used to seal the glass. The roaches like to be in close knit groups. So a smaller container is better than one with a lot of empty space. Blatta lateralis can be an excellent cricket size replacement roach. They grow fast and breed fast. Egg cases can be laid every 2 weeks and can hatch in 2 weeks. The higher humidity is needed for the egg cases so they dont dry out. Unlike other popular feeder species the lateralis are ootheca layers not live bearers. A lot of animals do like them, however some are put off by the defensive fluids they can eject while being eaten.
In closing switch to a plastic bin, solid colored and smaller than what you are using now. If you want something that gets larger as adults there are several other species available.
