I have a Flame Hawk that has been in my tank about 5-6 years. About a year and a half ago, he jumped in the overflow of my 140. I thought he had died and about six moths later, I noticed he was inside of the overflow. It took me a while to get him out, but I was able to return him to the tank. About three days later, he jumped back in the overflow. He has been in there now for about a year. He likes it in there, I guess. I just have to throw a little food in there each day and he is happy. I will get him out again, but will need to cover the overflow. I almost hate to do that, because I don't want to find him all dried out on top of the overflow cover when he tries to get back in. So, he is still there.
