You will need: Cardboard box Blue paint White card Colouring pens Pink card (or foam) Blue thread or wool Glue Sticky tape Instructions: Paint the inside of the cardboard box blue and leave to dry. Meanwhile draw or print out some fish onto the white card and colour in. Remember that coral reef fish are very bright and colourful! Cut some short lengths of wool and tape one end to the back of each fish and the  other end to the top of the box. To make the coral, cut some tree like shapes from pink card. see the photo above for guidance on the shapes. Fold over the bottom to create a stand-up base and glue to the bottom of the box.
