I have been thinking and I want to put some minnows from my creek into my pond when it's ready, but I'm also interested in setting up a native tank. I went down to the creek and caught 4 fish this evening and set them up in a 20 long. My question is, what type of fish are these? I just know them as "minnows", but I know there are several hundred species of minnows. So is there anyone here that's good at identifying wild fish? Here are 2 that were smaller, at only 1 inch Here are the 2 bigger ones. They are about 3 inches long. Sorry for the bad pictures. They are really fast!
