Yes, that is a chinese algae eater. They had it labeled "midget algae eater"??? That's a new one. Those guys are sold far too often to people looking for algae eaters, truth is, the older they get, the less algae they eat. They get very aggressive and pick on other fish. I've heard that as they age, they turn into carnivores and start preying and picking at other fish. Maybe ask to return them and tell them to rename their tag, that is terrible!
