I just put some airline tubing in my tank two days ago to get some bubbles going. The tube is against the back wall with a rock holding it in place. This one cory is obsessed. He wedges himself behind the rock directly in the stream. I thought he might be stuck so I moved the rock forward. Nope, went right back to it. Thought he was having trouble going backward outta there. Nope, snuck right back in. Any idea why he's doing this? Second picture isn't very good but I wanted to show he's against the back wall.
