I'm not that experienced looking at small minnow's but with the strip down the sides my guess is Bass.

I have a � acre pond and my channel catfish spawn . But you need to sink a trash can or several trash can's if you want lots of catfish in about 2 - 3 feet of water so the Channel Catfish can have their young in there and protect them until they can fend for their selves. Otherwise, as I have read the small fry just swim in a tight ball and the other fish eat them very easily. I never see my new catfish until they are about a foot long and start feeding with my really big ones.
