I had a large 6-7" foxface to move, so the little $30 acrylic tubes didnt look big enough to effectively fool the fish into entering.
I hate to confess this, but since I am a DIY'er , I took the time to make a sliding trap door trap out of scrap fiberglass equipement parts.. It took several hours, over several evenings, and maybe 5 dollars in plastic screws, ( so it could be dismantled for cleaning) and a threading tap, for threaded bolt holes.
Finally got it constructed, put it in my 150, and waited, and waited .. after 3 days my fox face entered, but scuried out when i tried dropping the door. After another 2 days... I caught him in a net.. LOL
So.. I now have a large trap.. 15x18x4 waiting for some future attempt to entice in a large fish.
