What is this Weird Saltwater Fish I cought?!?!?

In a creek in Gautier Mississippi I threw my cast net and this fish i caught was swimming around with the shad. He is no bigger than a shad and is the shape of an oval going up and down . He has one yellow eye on each side and has some brown spots on one side along with silver, but completely silver on the other, leading me to believe he lays on the bottom but I dont know. on the bottom and top there are LONG fin like things extending, and they are clumped so the look like a string of hair. He also has a standard tail fin shaped like a sideways V. and on the the bottom and top leading up to the hair like fins are standard fins covering from the tail to the hair fins. His mouth is lower down, not in the middle like most fish, so imaging an eye in the normal place for a fish, and than a slope outwards until we reach his mouth near the bottom, his gills come from right below his mouth, to above his eye. I will award 10 points!
