I have a two newts, both firebelley newts. I just put in the second one and they both seem to get along fine but recently my first newt, norbert, has been having problems. He keeps getting stuck in his rocks and will go into his favorite cave and stay in there for weeks on end. When i clean the tank, it takes hours to coax him out. I rarely ever see him wandering around his tank anymore and i don't know why. Any ideas?
