CD Fish Toy

Turn a CD into an enrichment toy for your fish! Determine the ideal location for the CD to hang in your aquarium and cut an air tube to the length needed. Attach one end of the air tube to an air pump. Feed the CD onto the other end of the air tube and use suction cups to attach the tube firmly to the CD. If needed, attach a buoy to the middle of the tube or a small weight to the end of the tube.
