Killifish ID help

I hope this doesn't double post, I just tried to post this but it didn't come up....I dont have better pics because these fish arent in my fish tank anymore. All fish caught on Long Island

I was catching all Striped Killifish one day, with a few Sheepshead Minnows mixed in, but this first fish here I didn't notice until later seems to have much fainter stripes than other Male Striped Killifish. Is this a Mummichog perhaps? Again, I didnt see any Mummichogs at all that day, but this fish seems a little different than the other Male Striped Killis

This other fish was caught in same situation another day, seemed to be all striped killifish there, this fish happened to be the only one i snapped a picture of and I didnt notice at the time but this doesnt appear to have any stripes.
