jaleely: he has yet to refuse a meal, although his feeding response is essentially "wrap head around warmed-up pinky and swallow". At least there's no hesitation when he bumps into one in his feeding tank.
Skumbo: I actually got the idea from a YouTube video where the owner fashioned a homemade hide from 2 toilet paper tubes crossed in a 'T' and buried it under the substrate for his hoggie. I thought Quetzal would appreciate the firm plastic hide buried under the coconut husk so he could make a tunnel that would hold its shape better. And he loves it!
Thanks for the kind words, everyone!
