Sorry it's not a better picture. It's hiding so I can't try again right now. I'm thinking it's a Pleco but I'm not sure. A coworker donated this fish to the office aquarium. Thing is she doesn't remember what it is. All she could tell me was it's an algea eater she bought after the last county fair. My concerns are how do I care for it and will it grow to big for a 20 long tank.
