Behavioral recording apparatus. (A) The observation container as seen on the recording. Two juvenile goldfish swim close to the front wall. The top view can be seen on the overhead mirror. The combination of both views is necessary to calculate the 3D trajectories of the fish. Note that the container walls to the right and the back are semi-transparent (to reduce mirroring) and the other two walls are fully transparent. (B) Schematic presentation of the radial zones: the center, middle and outer zones have an outer diameter of 1/3, 2/3 and 3/3 of the width of the container. The corner zone is the combination of the areas of the four corners outside the outer zone. (C) Schematic presentation of the locations of the four quadrants. Note that they have distinct characteristics in terms of walls (transparent or semi-transparent; the latter are presented by double lines) and in terms of the surrounding physical features (e.g. white carton on the back, green curtain on all other sides, different distances from curtain, and presence of the camera at one side).
