You are right George. Visits to the hatchery are great fun.

I like that helmet head male CNBG. \:D Those copper nose bars sure make them easy to id when spawning. Be sure to look for wider vertical bars, yellow/orange fins/tails , white/light fin/tail piping and count those fin rays when checking CNBG.

George was the truck close enough to the pond for the fish to see when Todd honked ? Sound is different in water. Travels faster but does not go no far before it dissipates. I wonder if it was vibration (low frequency)and sight. Sound connected to the water like a bang on the side of a boat or stomping around the pond edge or a truck driving up are transmitted by vibration into the water but unconnected noise like a hand clap has little effect on or penetration into water.
