Halbhecht. In den völlig transparenten Eiern sind die Bewegungen des Embryos und die Blutzirkulation gut zu erkennen. Nach dem Schlüpfen schwimmen die Tiere senkrecht mit dem Kopf nach oben. Eine Woche später ist die normale waagerechte Körperstellung erreicht. Außerdem sind Atembewegungen und Fressen zu beobachten.
