Draw an arch - top of a goldfish, then a small mouth.
Further we draw a bottom of a small fish from a mouth and we connect to the end of the top curve. Then draw an eye with a circle and three eyelashes, curve show the head of fish.
Draw the top fin and two curve a tail.
Then connect from below these curves the wavy line and draw one more fin about the head, and the second — is closer to a tail from below than a body.
Erase the line in a fin about the head and draw scales on a body at a goldfish.
