The big ones won't harm a 5" small one. They may, however, be hard to
catch! Even when Jim isolated several in a 'neck' in the pond, they
were hard to catch and promptly jumped out over a screen that reached
from the bottom of the pol to 12" above it! They can be torpedos.
Jim gets them used to eating from a 24" salt water net when he wants
to get them now. Then he can just lift it when they feed.
