Instructions
Measure the interior width and height of your goldfish aquarium using a tape measure.
Use a hacksaw to cut five rectangular pieces of 1/4 inch plexiglass to the interior dimensions of your tank as measured in Step 1.
Drill one 4 inch hole in each plexiglass sheet, using an electric drill mounted with a 4 inch diamond core drill bit. Vary the location of the hole in each piece, both vertically and horizontally.
Cover the bottom of your goldfish tank with 3 inches of fine aquarium gravel.
Install the first "level" of your maze by pressing one plexiglass sheet into the gravel in the center of the aquarium so the goldfish must swim through the drilled hole to reach the other side.
Place a food reward -- pellets or another treat food -- on the side of the plexiglass opposite your goldfish.
Add additional levels as your goldfish becomes familiar with navigating the maze.
