Lined Topminnow (Fundulus lineolatus)

    Found natively as far north as southern Virginia and as south as Florida, the lined topminnow is a member of the family Fundulidae. Although they have been introduced as an invasive species probably by people dumping their bait buckets into these freshwater systems.

    You can tell the difference between a male and a female by looking at the lines on their sides. The males have very pronounced vertical lines while the females vertical lines are equally noticeable to the horizontal lines which both genders have.
