Any idea what these are? I’m torn between round gobies and a type of sculpin. Found in a small creek in southern Indiana at my parents farm. I’m hoping they’re a type of sculpin because round gobies just get too big and I’ll have to figure out something to do with them. They have some beautiful coloration. It’s just really hard to get a good pic against the sand. Super active and pretty aggressive. I had a few shiners in with them that were caught in the same area but that didn’t work out very well. They have left the darter alone though. I’ve already quarantined, treated for internal parasites, and watched for any other signs of problems for at least a couple months. They took to frozen food right away but I did fling it into the water for the first week or so to make a splash and catch their attention. There’s two and they have slightly different coloration but could be male and female. They stay pretty close together.
