Lrrr is always preparing for dinner. And I feed them every other night so if they didn't get food the night before they know to expect it the next night. Glurmo will sometimes just sit patiently on a vine, but Lrrr will either sit dead center of the floor of the terrarium and look at the doors or he sits on the vine above his spot on the floor staring at the door. They like to let me know when they want food!
