So this photo is at night to show some behavior that I have a question about. This is what it sometimes does during the night. It looks like its stretching to try and get lower in the tank. All that's lighting the tank at night is 4 moonlight led's. Just a little extra light in this shot provided from the kitchen so we can actually see it. Considering the fact that this nem is stubborn and will not move from that hole to save it's life or put itself in more desirable conditions, does it look like it needs to move lower in the tank? Should I move the rock down to the substrate? During the day it shrivels up as if it's trying to get away from the light so I put a rock overhead to cast a bit of a shadow on it and now it does not shrivel up as much. But it does this at times during the night. Any suggestions?
