Have you ever caught any spotted bass? (Also known as Kentucky bass.)

The second fish might be a spotted bass. Or even a spotted/LMB hybrid.

Next time you catch an obvious LMB, pull erect the front dorsal fin. You will notice that the tail end of that fin comes all of the way down to the back of the bass, before the start of the second dorsal fin. This is true even for very large LMB.

When you catch a bass that has odd coloring (to your eye), do the same thing again. If it is a spotted bass, then the back edge of the front dorsal fin will merge (a little) with the front edge of the second dorsal fin.

That "might" be the case in your second photo - if you had pulled up the last dorsal spine with your fingertip. (I can't tell for sure looking at your picture.)

Black bass species can have widely varying colors and pattern manifestations depending upon the water conditions. I have caught LMB and spotted bass throughout the day on a reservoir from shallow muddy conditions where the river was running to clear deepwater conditions near the dam, and there was huge variance within each single species during only a single day.

If you do catch an obviously "spotted" bass, do the dorsal fin test I described poorly above. Your eye will quickly become calibrated on identifying LMB versus spotted bass if your start catching a lot in your best fishing spots.

Good luck catching bass this spring. Those two little fish are clearly nice aggressive chunks that I hope you catch again in 3-4 years!
