I keep a lid on my overflow for just this reason. My foxface got spooked and jumped out of the water. In the process he knocked the lid off of the overflow and fell in. He's about 5 1/2 to 6" long. Any net he can fit in will not fit into the overflow not to mention he just goes through the pipes to the other side where you can't get him. He eventually got angry at being chased and flat out went bezerk on the net attacking it with his spines, bruising and scraping himself up in the process (just glad it wasn't my hand ). I let him be since I was just stressing him out and not accomplishing anything. At first I thought he was in shock but he is still ok for the moment (minus the scrapes and being extremely confused). Now, any suggestion on how to get this sucker out?
