The door is a peice of 1/8 in plexi from home depot. I sandwiched two 1/4 in pieces together with thin strips of 1/4 in leaving me a slot down the middle that allows the 1/8 in plexi to slide up and down. I tied fishing line to the door with a fishing weight on the end that hangs outside the tank to hold the door open. When the subject enters I just released the tension and then fish FREAK OUT, but it was better than chasing them all over the tank with a net. Ill get some pictures up tonight.
Chris,
Sorry I didnt know he had a thing for zoas. Are they at least earning their keep? Need to borrow the trap?
