I was buying 2 new Cory Catfish a few days ago and the store employee accidentally scooped up this fish with one of the Cory cats and put it in the bag. When I got home I seen it and wondered what type of fish it is. I put it in my 30 Gallon tank with my Rosy Barbs and Zebra Danios. They seem to get along fine so far.
I took a picture of it by itself and one pic of it right in front of one of my male Rosy Barbs and above a Zebra Danio for size comparison.
What fish is this? Can you tell me more about it?
