Folded from a 20 x 20 kraft sheet.
During the same conference as the butterfly, I started playing with a bird base, and an angelfish started to take shape!
Of course, I had to make it a French angelfish, so I changed the four points to bring out different fin shapes.
Therefore, the model is not symmetrical. The four points of the bird base respectively form the dorsal, caudal, anal, and ventral fins.
