The trap can catch a lot of different worms. Use a backup net to catch any worm that's not entangled. There's absolutely no reason for you to start over at this point. Also, you never really know the health of a fish, especially one that hasn't gone through proper QT. Btw, I've had a Wheelers and a Tangaroa jump through the mesh of my lid or through the gap between the lid and glass, only to find them on the floor.
