Very fascinating. It reminds me of a time I was fishing a clear deep pool in a creek I occasionally fish. I dropped a fly along a tangle of branches and a big largemouth popped out of the tangle to grab the fly, but before he could suck it in a slightly smaller small mouth bass darted up from below and struck the largemouth. After a short battle the largemouth backed off to its laire and then the smallie retreated, leaving my fly alone. This played out a number of times until the largemouth finally was able to grab the fly. I returned the bass to the creek and it swam to its home. I tossed the same fly and a couple others in hoping to attract the smallie, but it didn’t show itself. I tried again about 30 minutes later with no luck. It was almost as if the smallmouth didn’t want the fly , but it didn’t want the largemouth to have it either.
