Unlike most fish species, the angel fish, a native of South American waters, has a body that can be described as triangular in shape, when viewed from the side. To make this angel fish, the waterbomb or balloon base is used, which creates the body of the fish. The tail is then formed to complete the model.

If you are using two-sided paper, make sure that the side you want for the outside of the fish is facing down before you start to fold.

NOTE:  This model starts from the waterbomb or balloon base. If you are able to achieve this without instructions, fold the base and then go to Step 9.

1 Place a square of paper on your work surface and position it so that the edges are facing up and down, left and right.

2 Bring the top edge down to meet the bottom edge. Crease and unfold.

3 Bring the left edge over to meet the right edge. Crease and unfold.

4 Turn the square over and position it so that its points are facing up and down, left and right.

5 Bring the left point over to meet the right point. Crease and unfold.

6 Bring the top point down to meet the bottom point. Crease and leave folded.

7 Grasp the left and right points of the resulting triangle and push inward. The model should collapse along the pre-existing folds. The result will be another triangle shape that has one folded flap sticking out from the back of the model and another sticking out from the front.

8 Fold the front flap to the left and fold the back flap to the right so that your model will lie flat.

9 You will have a triangular shape with 4 separate flaps. Rotate it so the point is to the left and the long side to the right.

  10 Out of the 4 flaps of the triangle, you will be working with the top and bottom points of the top layer only.

11 Take the top flap and fold it over so its edge falls just below the horizontal center crease. A long, triangular point, the first fin will form.

12 Similarly, bring the bottom flap up at an angle and fold it over the fin just created.

13 Crease everything well and turn over.

14 Children can decorate this model by adding eyes and stripes using visual or tactile methods.
