When they move the water bowl (cap) just so that they can fill it up with dirt!!
How often do you have to give them water @spottedbull ?
The little guys sit on a shelf next to my desk chair, so if I see the bowl needs attention I fill it.
That is awesome but terrible I have to ask, which tarantula is this?
Lasiodora parahybana sling. She’s about 1" at the moment, maybe smaller. She has all that area under that cork bark excavated out and flattened down. Its pretty cool.
