No Seminoles are not necessarily green. Certain populations may have a greenish cast though as adults. Seminole killies are one of the largest grwoing NA killies, reaching approx 6 inches. I have caught a schol of monsters like this and they were impressive. The reason I feel so confident about this fish is due to the "beak-like" snout. There are only two fish in the SE that have that type snout, one is the seminole and the other is the banded killie(F. diaphanus) but these have their southern end of their range in northern SC. They have not been taken in FL, or even GA that I am aware of.
