Your little cutie looks a lot like the baby bristlenoses at the fish store where we bought our longfin bristlenose. They occasionally get some of the names right (however rare that may be) and it looks like this is one of those times. Very, Very cute! And we love ours, she's just about everywhere during the day, unless like most other species of pleco (who are mostly nocturnal)
Also, ours is about 3" and is just now getting bristles.
