They roam. 730-8pm heads (all 6) pop out of their hides like they just woke up and waiting for darkness. Then when its lights out they roam around. All my displays are a simulated environments so they're exploring up,around, under branches, logs etc. All lit up in red, it's like my whole wall comes to life. Pretty cool actually. By the time i wake up they're all back in they're hides. Same thing every night, unless their in shed obviously.
