You are correct, it is a zebrinus, the site I pull the pic from has the pictures reversed.ksiaquatics;516001;516001 said:The bottom picture is not a marsh killie. If I'm not mistaken, that's Fundulus zebrinus, the plains killifish. Regardless, it is certainly not confluentus.
He said these killies were already bigger than his puffer. Confluentus maxes out at 2-3 inches. Whereas, mummichogs get 6 inches easily. I'm sticking with mummichog. Is there any way we can get a better pic?
