Need help with a fish ID

[njstew2]

Wondering if I could get some help to ID a fish I've never seen before. I caught 2 of these in the Manasquan river on a worm. It was about 10 inches long, mostly silver in color and darker towards the top. It had a similar shap to a sucker, only it had a forward facing mouth and a thicker head. The odd thing was the 4 yellow spikes it had on its head. The pic is a close up of it's head. I've fished this river for over 30 years and have never seen one of these.
I did some internet searching and came up empty. You guys always come up with with the answers to these questions.
Thanks!
