How often?

[RedCapTrio]

I do that with all of mine. Have to since they're all pretty much crammed on top of my son's dresser until the contractors get off their asses and fix the wall in my room To get the lids off they have to be moved. I turn them all so their burrows (if they burrowed agains the side so they can be seen) aren't facing each other. Not sure if that matters, but i didn't think it'd be good to have 2 different species staring each other down with less than an inch between

Hahahah, makes me think of fighting fish kept side by side in petshops. I wonder if it will have an effect if kept facing each other...
