Okay, we put 2 dozen minnows in our pond. We have a fish that doesn't appear to be a minnow. Actually, he HATES the other minnows. He has definite wide vertical stripes, shaped rounder and his color appears to be black, beigey/pink. He has made a home under some flat rocks and chases any minnow that comes near. We had to have picked him up with the minnows. Does anyone know what type of fish this could be?
