4. Fold the colored paper along the diagonal to form a triangle with one corner missing.
5. Fold one side of the triangle up at any angle, but don't fold it in alignment to accentuate the shape of the fins on the back of the fish.
6, try to be symmetrical on both sides, so that the folded fish is beautiful.
7, fold up the unfolded corners to make the tail of the fish.
