I have an Albino Plecostomus that was sold to me as a bristlenose so I thought the max length would be 5 inches. When I look at bristlenose pictures elsewhere mine does not look like them. I got it in January and it was about 2 inches. Can someone help me with how big this will get so I can plan my future tank size appropriately? I currently have this pleco and a green terror in a 46 gallon tank.
