You only lip a bowfin once

that's definitley a Pleco. Very common in aquarium shops.

Florida is over-run with non-native fish in their southern waters, including Oscars. i can testify to how good they taste too :D Some fine eating. I'd take them over crappie anyday.
Great part about the non-natives is that there is no limits on them and most of them, at least the cichlids (Oscars, Mayans, Tilapia) are fine eating.
