Yeah mine do that to.. they're just chillin.I've had mine for a year and a half now, and they don't really do anything but eat, so I try different ways of feeding them and have fun with that. I used to mist my WTFs just before feeding every day so that they would be expecting food every time I spray, making them more active, but I went through alot of crickets feeding daily, so now I feed them less often, but I still mist regularly, and the misting allways gets them going.
