Pat at Reef Life has a "loaner" fish trap...I don't know what the logisitics are though. You could call there and find out. I also have had success with the "soda bottle" fish trap. I make it out of any size of clear water or soda bottle (depending on the size of what you want to trap). Just cut the top off...below where the taper evens out...and flip and insert back into the bottom of the bottle. I attach one side with fishing line and the other with a piece of tape. I leave enough fishing line so that I can make a long piece with a loop for retrieval. It's worked great many times for me for inverts, fish, etc. You can also cater the size of the trap to how much room you have in your tank...I don't have much room, so I make them out of the typical sport type water bottles.
