I caught my foxface twice using the jar method. It was harder the second time because he knew what I was up to. I had to get a big half gallon jar (glass) with wide enough lid and put a clip of the sheet of algae that he loves. Then I tied a long large string around the lip of the jar, sat six feet away on the couch and waited. When he went in, I pulled the jar up with the string to the top of the tank, I was able to lift him out, and I outsmarted him again. Good luck!
