I’m going to say that at times, they do some pretty unique things. I have some that have lost the need to “hide”, literally almost always in the open. Most, if not all the balls I have will sit in the open if they make waste in any part of their tank unless it’s in their water dish, and even then they will still remain visible to it’s cleaned. One prefers to hide constantly, but again makes it known if he’s hungry, or peed in his hide. Also have a couple who seem a little to eager at times to get out of their tanks. One that isn’t a fan of returning to his tank till he’s ready. So to some extent, definitely some different behaviors.
