Tank temps drop into the mid 70's at night, but daytime temps are mid to upper 80's on the warm side and low 80's on the cool side. Right now at 8:30am it's 86/78. Sound ok? I've been sitting at the computer for about an hour and I've had one little piggy cruising the tank the entire time surely looking for food even though they were just fed yesterday Wow, he just settled on top of the rock to bask for a minute. I love having them on my desk
