Talk:Fish curve

The parametric equations of the ellipse were exchanged with those of the fish curve...

In addition, the wrong cartesian equation of the fish curve may be replaced by

$$ 4 \sqrt {2} a^3x+2a^2(x^2-5y^2)-(2x^2+y^2)^2-2 \sqrt {2} ax(2x^2+5y^2)+2a^4 = 0 $$...

Finally, perhaps it would be appropriate to use a more general equation, dependent on two parameters, to see in this case as varies the shape of the curve...
