I bought some acrylic and acrylic glue and made a fish trap that was rectangle in shape and about 3 in inside diameter and then glued a piece on that would allow the trap to hang on one of my center braces and be suspended in the tank. I cut a slot in the top of the rectangle trap and cut a piece of acrylic that would slide down to create a door. Tide a piece of fishing line to the door. Put some frozen mysis and rods food in the back and sat about 10 feet away and watched.
After about 2 min of the food smell I had blonde naso tang, flame angel, hippo tang, anthias and many other fish swimming in and out. All i had to do was let go of the string and the door came down trapping any fish.
Works great!!!!!!
