just did a bit of reading on warmouth , seems they can hybridize across the board !
one information source said largemouth , black crappie and all the other sunfish species can hybridize with them !
and NONE mentioned blue streaks in the gill plates as a feature of identification on a the pure warmouth .
the red dot on the rear dorsal fin that is commonly seen in the spring indicates its a male fish.
as well a bright red eyes during the spawn ....said they reached spawn capability at 3 to 4 inches long
and 3 spines on the anal fin says it isn't a rock bass
