I can feel how that is, having some hands on experience in the pond....
My hubby had to stand in the middle of our 1200 gl above ground pond to catch my 12 inch comet out, since I wanted him with my in the new house, so he stood there, big net in his hand, and was trying to get something that was just as fast as a koi! The koi must have thought this is something new to inspect, and they were all swimming around his legs in a big clump, and he had a hard time even spotting the comet among all the other shades or red and white. I bet they laughed at him too!
After 20 min he gave up, decided another approach. He threw some pellets in, and after everybody came for his food, he finally was able to get the comet...But it must have been such a funny site!
BTW, pond netting is really the safest way to go. They might sell similar fabric at nnnnnn, but you never know what components are in that fabric, and there is all kinds of stuff it might give off when it rains on it....
