So i was watching my tank before bed and the lights had been off for about 4-5 hours. My g/f and I noticed the guy swimming about up and around the tank throughout the night. I got up and sat next to the tank. He was right next to me just sitting ona rock, then he proceeds to go up to almost the top of the tank and literally dive bombs onto the rock. It looked as if he knocked himself out. I got the flashlight on him and he didnt appear to be breathing. About 2 minutes pass and he awakens and goes down into his home and sits there. He doesnt look like he's breathing, and doesn't respond to a flashlight.:grumble: Anyone got any ideas?
