I have no clue as to why I didn't buy one before, but picked up one of those minnow fish traps of black mesh, coned ends with hole in the center going into the trap, & then you hook the 2 pieces together. Put some fish food in a mesh bag & hung it in the center. I've already caught around 50 goldfish sizes 1-2" without standing there sweating like an idiot, LOL. 2 different ponds & left the trap in each pond for about an hour. YEAH!
So if you've got way too many babies in your pond try one, it's only about $7.
