As soon as i drop the roaches in they hide in either the rock log or get under the carpet. The little suckers hide before she can eat them. Or maybe she just isnt hungry? I have tried putting her in in a seperate area to eat so they wouldnt hide but she was way stressed out and tried getting out. I also tried feeding with these tweezers things and shes not interested.i would hate to take everything out at feeding time because i read it could stress her out if things get changed in her tank. I have only had her for 2 weeks so i really wouldnt want to stress her out anymore
