The steps you've already taken should help, I just like listing all possible options.

For the sake of cover, plastic greenery from your local craft or dollar store does them just fine, as does options like balled up newspaper or paper towel. Matching hides can be vital since they do need to be somewhat snug for a BP to feel secure, so if one hide is more enclosed or fits more snugly than the other, that can lead to the BP favoring a particular hide or resorting to options like using in/under its water bowl as a hide.

Usually not a major issue, but such behaviors CAN lead to bad situations like regurgitation, since the BP may not feel secure in its hot hide and thus may not have the temperature needed to digest.

Ultimately, I'd suggest either the RB hide here, options from ExoTerra or PetTech here, or doing as I do since mine is still growing: rigging something up out of opaque tupperware, plastic takeout containers, little plastic boxes from the dollar store, rodent igloo houses, or various other options. Like mine are $2 cheap dog bowls from a local store that I cut the bowl area out of then cut a little door into. To show how that worked:

this dog bowl + scissors/lighter = this hide
