I said no, but I don't think you have a problem. I am also one of those guys who can sit and stare at a tank for hours. Used to crack my wife up. One tank I had I would lay on my back with my head in the stand with a flashlight to see the worms crawling around in the sand. I'm pretty sure she thought I had a problem then.
Sometimes I can’t focus for anything and can’t seem to get finished with the dozens of tasks that need to get done.....Then I pass by the tank and it like a Gypsy Hypnotist is inside. The house could be on fire and there I am...just staring away.
